Is there a way to lock transverter ports to a particular transverter defination?

Tom Worthington

I have two transverters connected to my 6600M, one for 2m and one for 70cm.  Unless I were to change to connections on the back, the 2m transverter will always want to use XVTRA connections and the 70cm will use XVTRB.  Much of the time the radio seems to remember this and connect appropriately when I open a slice on either 2m or 70cm, but not always.  Especially when I am trying to do satellite communication I'll look over and see that it has changed either the receive or transmit connections to the incorrect ports.  
(Thanks for having the 4th transmit keying line in the ACC connector.  I have 2 HF amplifiers and the two transverters so I use all 4 of those connections)
