I don't think this is possible from all of my searching.. But hopefully someone can prove me wrong!
I think Plans are a valuable tool, however, I find they can get bogged down quickly when working with multiple spaces.
My goal is to have a filter that will pull in a Space, and all items linked to items within that Space to track dependencies and have a high level view of these items.
Is there any way I can do this without Scriptrunner? Also, these are not Epics, they are stories/tasks.
Plans are such a powerful tool, it boggles my mind a bit that this wouldn't be possible as it seems like such a great use case.
I assume this is just along the lines of JRACLOUD-18679 and is not doable without an add on.
