payments in plan are scheduled for same day/frequency but not combined?

[TheOtherDoctor]

I have setup four payments, two pairs each with same frequency/amount; Two of them are listed as "automatic payment of X Eu split between A and B", the other two are not combined and each listed separately, although to be done the same date. I worry that those will actually be drawn as two transfers, thus resulting in twice the transaction cost, which would be a waste. Please consider checking if combination of same-day transfers is working... if this is not yet implemented, I'd suggest to do so... or is there a way for users to recreate plans to assert same-day transfers minimize bank costs?
