Bill Splitting Adjustments

I love the bill splitting feature.

One of its flaws is that if you split a bill with someone with a Monzo account and they pay you back from a different banking account, there is no way to link that payment to the original bill split.

I would have to cancel the whole bill split, therefore removing the record that there was a bill split on that transaction.

My suggestion is:

Can we have the ability to link an incoming payment to a pending bill split transaction?
