Thanks for posting – fair enough request. Can’t promise a timeline at the moment but it’s a logical feature idea.

There's a way to do this. If X got a refund for $m which has to be split between X, A and B, create an expense with X, A and B paying $(m/3), but the expense is owed only by X. That way X has to settle up with A and B.
