For invoices, I would like to be able to split the invoice amounts within projo into my own order amounts and sub-planner sums. It is already known to the billed service whether it is attributable to the sub or not. In the invoice summaries, I have no idea what amount of the invoice was actually paid by us and what proportion must be passed on to the subs.

We often have to provide the tax office or insurance company with our invoice amounts with and/or without subs and a split presentation would also be useful for our own clarity.
