Using groups analytics for objects instead of company, account, team etc

Hey there Mixpanel Community 👋

First post here !

So I’ve setup Mixpanel & Segment on our product (more than 12k users)

We use Group Analytics to group users into teams, which is super useful !

But I’m encountering a big problem

In our product, users can create campaigns.

We have the following campaign-related events:

• Campaign Created
• Campaign Launched
• Campaign Deleted

In those event, I’ve added a property called campaign_id

I thought I was going to be able to group campaigns with this property to follow campaigns trends (What is the % of campaigns being created and deleted later on? What is the % of campaign created but not launched ?) 

But it seems you cannot do this using a id property, or maybe you can ? (first question !)

An alternative I thought of was to use Group Analytics and to create a Campaign Group, so that would allow me to do this, but I’m not sure if this is a correct solution because a it’s only for those campaign events that it makes sense (only 10% of my tracked events), so I would either add a random campaign for those other events or add a null value, is that even possible ? (second question !)

Thanks in advance !
