Move underspend on Targets to corresponding Pot

So if I set a target, say X hundred a month for Groceries its likely that some months will be under and some over. It would be great if I could link these targets to pots so that when we underspend money is moved to that pot so I can cover the months when I go over my target. Could apply the same the other way so that if you go over, money is moved from the Pot into the account to cover that overspend.


I’m sure you could do something like this in IFTTT - but you would have to do it based on a transaction, not the overall target… it depends how much effort you want to go to
