Bulk edit issues to assign/unassign an Epic
Problem to solve
As a user of the Issue List, I'd like to edit the Epic value of multiple issues at a time, so I can bulk > assign/unassign issues to epics
Now that we allow users to filter by an epic (#195704 (closed)), we should enable a bulk edit feature as well.
Add the ability to bulk edit epics on both Project and Group issues pages.
Permissions and Security
Same as current bulk editing permissions
Update existing Bulk edit docs
