I got a "Theme" custom issue type.
The "Theme" is above the epics level.
I got a automation rule that every new label in the theme issue type it automatically add it to the hierarchy below.
(e.g. to all the Epics and their child Tasks/Stories/Bugs).
I'm not sure how to create the opposite way, when a certain label removed from the "Theme" I would like to remove the exact label from all the hierarchy below.
