I was sure this would be already posted somewhere, but couldn't find it - if it's a dupe, my apologies.
Currently moderators have the ability to lock a question or answer with one of several canned reasons: for instance, a "historical lock", for questions which are no longer considered good or on-topic but which are kept around because they have some historical value; or a "content dispute" lock, for questions which are currently undergoing edit wars.
But locking a question is an unusual thing to have to do, so all of this is just about edge cases. And of course edge cases are all special and different from one another. Questions may need to be locked for many different curious reasons, not all of which are covered by the existing canned "locked post" banners. Sometimes it would be nice to be able to create a special banner which only applies to one particular edge-case question, or even to tweak the text of one of the existing banners slightly.
Would it be possible to grant moderators the ability to customise the "locked post" banners?
