Hi Tobias, Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so.

Yes, you can use "current_domain" as a group key in Mixpanel. A group key is the property that connects event data for Group Analytics. It can be any property that is common to a group of users you want to analyze. However, you need to administer group keys through your Project Settings in Mixpanel. All events need to have a defined group key on them in order to be attributed to a group. Group keys are project specific, and the group key should be set up before group data is sent. To administer group keys, navigate to your Project Settings. Click +Add Group Key under the GROUP KEYS section. Please note that Mixpanel does not backfill historical data before the group key was implemented. For more information, you can refer to the Mixpanel documentation on Group Analytics for different SDKs like Javascript, React Native, Java, Node.js, Go, Python, Flutter, and iOS (Swift).

Let me check the knowledge base for you again. One moment! 📚

You can inherit properties from other events using Mixpanel's Borrowed Properties feature. This feature allows you to "borrow" a property from one event and apply it to another, enabling you to analyze as though that property has been tracked on that event all along.Here's how you can use Borrowed Properties: 1. In the Mixpanel UI, select the event you want to analyze. 2. Choose to borrow a property from another event. This property will now appear as if it was tracked with the event you're analyzing.Please note the following: - Borrowed property creation is limited to Admin & Owner Roles only. - A project can have a maximum of 20 borrowed properties. - A borrowed property once created is like any other custom property. It can be accessed by all in the project depending on permissions. - Borrowing of a property is strictly from the most recent event in the 7-day lookback window.For example, if you want to borrow the property "search term" from an event "search product" for the event "purchase", the property will be borrowed from the most recent "search product" event where the property is set.To use a borrowed property with other functions, you would need to: 1. Create a custom property with just the borrowed property on its own. 2. Create a separate custom property using the borrowed property (i.e., the 1st custom property).For more detailed instructions, you can refer to the Mixpanel documentation on Borrowed Properties.
