Disputes - Strategies on Hold

Hi,
Newbie when it comes to Advanced Collections...

They want to put dunning letters printing on hold when placing invoices in dispute but already before credit memo creation as at this stage the invoice is still under investigation and might or might not be credited.

There dunning letters are setup through strategies so they do not use the dunning setup so therefore the strategy should be put on hold that produces the dunning letter printing.

Is there std functionality that can cater for this?

Thanks
Charmaine
