Retroactively Edit Domains in Custom Rules [Feature Request]

Currently, the domains in custom rules already created cannot be retroactively edited. If I have to retroactively edit the domain, I have to delete the respective custom rule(s) first then recreate the respective custom rule(s) with the edits (before I save the respective custom rule(s); otherwise I have to go through the whole delete/re-add process all over again just to edit the domain
