Reverse credit allocation in purchases

Hoping I can get some guidance please.

A supplier credit was inadvertently allocated to oldest invoices when a payment was about to be made.  Is there a way to reverse this allocation (made across a number of invoices) to reopen the invoices so that the credit can be reallocated to the correct original invoices?  I think I mean like and undo/redo situation?

Unfortunately, one of the invoices the credit note was allocated to an old invoice that should have been deleted in a prior period (was a double up).

Hope that all makes sense!

Thanks in advance
