That would be nice. I get all these small transactions, especial from the POS interest. It would be nice to be able to easily combine them.
Combine them? Can coin control do that?
You don't need coin control to do that. You can just make a payment at the amount of your entire wallet to yourself, it basically groups all the small coin blocks and puts them into one big one, although as you stake, big blocks break and smaller blocks generate so it's really not necessary.
