Routing tables work very good. And they can be further improved

Currently, routing tables work with gl code, cc, pc and supplier. However, we are still facing situations where all of these dimensions are the same, but we still need to send the invoice to different people. This holds true for our telephone invoices. The first approver should be the employee that is using the phone. However, that employee may share the same cost center with colleagues. That is why i am asking if routing tables can be expanded to look for more details.

My idea, is to use a text string . For example, if text Daniel exists, then send the invoice to Daniel). As a result, we can send the telephone invoices to the correct first approver, even if the gl, cc, pc and supplier will be the same
