TNEW V6 Gift Certificates

Does anyone know if there is a way to control the Gift Certificate payment mode by performance or Production? 

I see in the TNEW_DYN_PAYMENT Method system table, that can control credit cards; but am wondering if there is a way to control Gift Certificates? Or is there only ApplyGCatCheckout in Site_Controls -  TRUE/FALSE?

Scenario: We are a presenting, producing and rental house. For our rentals I would like GCs not to be redeemable online for their performances.
