Watchlists for AR standard invoices

Hi Community

Is there a watchlist which can be created for AR invoices entered through the standard invoice entry application which are on hold. How can the watchlist be set up if possible

Also is there some notification that can be attached to a manual invoice record which will indicate that it has been printed, I can think of running a statement against it which would be a manual process, but can something mark the record when the invoice is initially printed like the status change on an invoice record from the sales order system

Thanks
