Review Changes not reflecting change in Parent (Epic) Link

[Brian Charniga]

Hi, I'm concerned about potentially impacting an existing Parent Link (Epic Link in this case) of an issue without realizing it due to Review Changes screen not reporting a pending change.

The scenario - I have an issue that was created in Project A that is a child of an Epic in Project B. I don't currently have Project B in my Advanced Roadmaps Plan scope, so I'm not seeing the relationship that exists - and I had no idea Project B even existed (my org has many many projects). One day, I inadvertently change the parent Epic of my issue to one that is in Project A because I don't see any relationship to Project B in my plan and when I do Review Changes, the "Current" state is reported as empty ("-") so I assume it is safe to apply the change. 

Is there a way to ensure I will be warned about overwriting a potentially important associations with external projects - without being required to have full visibility into external projects that I may or may not be aware of?
