Hello everybody,
I've currently got two lists:

The issue tracker is the main list where I've got my app build-on. Now I want to prepopulate the app when someone chooses a certain Project the Assigned user(s) will automatically be filled in (can be multiple).


I've linked the Project with lookup, so if I add a project to Project Details, I can choose this in the Issue Tracker list.

I need it this way so members can easily add stakeholders to a project.
Is this possible?
Thanks allot
