I've seen those before. Thats the reason I prefer a separate block for each revision entry, since trying to shuffle each revision down a line requires a lot of work on the part of the user. When something like this comes up, time for some automation to handle the re-shuffling.
Regarding the initial question, I don't think any dialogs in AutoCAD use the "click and hold" method. Maybe some sort of sort order template that can be saved out and re-applied later on...
