Can partial amounts from different AP or AR Invoices be selected for AP-AR Netting?

We have a requirement wherein partial amounts from different Invoices are required to be selected from AP or AR Invoices for the purpose of AP/AR Netting, i.e. let's say 30% from AP Invoice 1, 50% from AP Invoice 2 and 80% from AP Invoice 3 is required to be net off against similar applicable % from AR Invoices. how can this be achieved?
