On a flows report, can I add custom filtering criteria for subsequent steps? Specifically, I’d like a report that starts with Step 1, and shows conversion to either Event A with property B OR Event C with property D.
Based on the knowledge sources available, I can provide a partial answer, but there are some limitations to note.
Filtering in Flows
The Flows report does support global filters (applied to the entire report) and inline filters on steps you explicitly add to the query. [Flows Overview]
However, the knowledge sources do not explicitly describe the ability to apply per-step conditional filtering on intermediate/subsequent steps in Flows the way you're describing (i.e., "show conversion to Event A where property B = X OR Event C where property D = Y").
A Potential Workaround: Custom Events
The closest supported approach would be to use Custom Events. You can combine "Event A filtered by property B" and "Event C filtered by property D" into a single custom event, which could then be used as a step in your Flows report. [Custom Events]
Specifically:
Create a custom event that includes "Event A" (filtered by property B) and "Event C" (filtered by property D).
Use that custom event as an anchor step in your Flows report.
This would effectively let you track conversion to either of those two conditions as a single step.
Recommendation
If you need the granularity of seeing Event A with property B and Event C with property D as separate paths in a single report, the Funnels report (rather than Flows) may be better suited, as it supports inline filtering per step and comparison events. [Funnels Advanced]
The knowledge sources do not contain enough detail to confirm whether Flows natively supports the exact per-step OR filtering logic you're describing beyond what's outlined above.

The knowledge sources do not contain enough information to answer this specific question. They explain which custom events can appear in Flows (only shared custom events, and only the 50 most frequently queried ones) [Custom Events in Flows], but they do not specify a timeframe for how long after creating a custom event it will become available in the Hide Events section of the Flows report.
For a precise answer, I'd recommend reaching out to Mixpanel Support directly.

So if its not one of the 50 most queried events it won’t show?
That's correct, but with an important nuance — this limitation applies specifically to custom events appearing as intermediate steps (i.e., steps Mixpanel automatically surfaces in the flow), not to custom events you manually select as anchor steps.
Here's the breakdown from the docs:
As intermediate/automatic steps: Mixpanel only considers the 50 most frequently queried custom events in the project for automatic display in flows. If your custom event doesn't make that list, it won't appear automatically as an intermediate step. [Custom Events in Flows]
As manually selected anchor steps: You can still pick any custom event directly in the query builder as a start/end event, regardless of query frequency. [Custom Events in Flows]
So if your custom event is new and hasn't been queried much yet, it won't automatically surface as an intermediate step — but you can still manually add it as an anchor step in your Flows report.
