We imported our JIRA instance from Bugzilla, so a bunch of bugs have the External Issue ID field set. We want that field to be visible when viewing a bug.
But the External Issue ID field is also visible on the Create Issue screen. There, it's pointless clutter; by definition, any new bug that we file can't have an imported External ID.
Is there a way to hide the External Issue ID field on the Create Issue screen but leave it visible when viewing bugs?
