Is there a way to select project shown in drop-down of a Project Picker custom field

[Patrik Grönvall]

I have a custom field "Requesting Project" of the Project picker.

The problem is that this drop-down shows all projects in out JIRA instance, including all projects that are finished, and just archived as "read-only". This list will continue to grow as we run more projects through our process.

What would be nice is to filter this drop-down-list upon "Project Category", so, for example, I can filter out all projects with category "Archived" from being shown in list.

I made some effort using Behaviours (Scriptrunner), but got stuck.

Is there anyone out there who has a solution, or at least some ideas for me?
