Ability to sort messages

It would be great to be able to move messages (Campaigns > Messages) so I am able to sort them as I wish to, rather than have them sort based on when they were created. 

I think of my messages in sequence - what order they go in, by market segment. When I create a copy of an existing message for a new group, it goes to the bottom of the list since it's new, away from other messages that are in that sequence.

In short, I want to be able to sort messages as I wish to see them, please.
