Does anyone have a good method of handling invoices on hold in paperless?

Does anyone have a good method of handling invoices on hold in paperless. We want to get them into AP in order to follow the matching principle and recognize revenue. Currently the Project Manger has to approve them and notify us that that they need to be put on hold in AP. And once they are ready then they nofity us to take them off hold and pay them. We have them sign for them. But this seems a cumbersome and inefficient. It did put in a request for a product inhance to allow paperless to export an on hold invoice, but don't know if that can be done. Does anyone have any better ideas? feel free to email at [email protected].
