PO is invoiced multiple times with higher value with different reference

In a few scenarios, the user has posted multiple invoices for the same PO. The problem was that the reference field value was different in all the invoices and therefore error for duplicate invoice check did not come.

What if I want to put a check (to stop) in MIRO if a total of multiple invoice values for the same PO should not exceed the PO Value even if the reference in MIRO is different.
