The ability to move money between pots

I made a little idea post for this one, please vote in case it helps bump it

Pot to Pot transfers

So hopefully I haven’t missed the blinkin’ obvious here but I’d like to be able to transfer money from Pot to Pot. For example: my round up pot is looking healthy so I’d like to move some of it to a pot with a saving goal. At the moment I have to do two transfers instead of one.
