making tags moveable under different levels would be useful for changing them under a different level group. currently we use tags to assign budget managers to certain reports. They may be under a different group level and then may need to be changed to move to another level. Since how we structured original levels this now is a problem reassigning them to a new level without have to create a new tag under another level and then reassigning the new tags and removing the old tag.
To add to why this should be done. We use tags to assign persons names to reports. Now we have quite a few names in that list (and some multiple names with different roles). In order to make sure they are all in that list when we go to Manage Tags, they need to have them in alphabetical order so as to easily find them (and find them easily when selecting their name when filtering.
Please consider this honestly.
