If Confirmation upon Payment is active, using Direct bank Transfer, status of reservation should be Pending for Payment (not Confirmed automatically) until Administrator gets some payment notification.
So far there is no such option, as the booking is confirmed automatically while using Direct Bank Transfer or any other offline payment method. The plugin “does not know” whether money have been paid and as the booking is completed the status is changed to “Confirmed”. I have passed your request for further investigation to our developers. If there are more requests from other users, we might consider implementing such option in one of the plugin future updates.
