So I have done some searching in the Community already and all of the posts seemed to be <=2013 and the answer was basically 'you can't do that'. I thought I would refresh the question in the Community.
Does anyone know if this is possible and if so how?
Any addon app that might achieve?
Any crazy workaround ideas? Such as the one that woke me at 4am today - "Maybe I could import the two values in as labels. Then I could JQL search all issue w/ select list pairs and use Bulk edit to set the values." Should work and oh what fun that would be to boot!
