can we exclude (in dispute) invoices for customer dunning?

I wonder if there is a trick to exclude specific invoices from the dunning evaluation.
Invoices are amended with a 'dispute' feature to resolve disputes on invoices. All customers have customer dunning procedures. A trick we use to prevent invoices in dispute from triggering the dunning module is to set an invoice dunning procedure on the invoices in dispute. That works like a charm, however, when there are long overdue disputed invoices AND another not-disputed invoice gets one (1) day overdue, the dunning module kicks in and seems to evaluate all the customer invoices regardless of the invoice dunning procedure is set or not and want to send and dunning letter for the 1-day overdue
