As two rudder servos may work on Ch4 and Ch7, the rudder digital trim can only be assigned to one channel so this is a problem I have setting it with my 9Z. There seems to be no way of assing the T4 digital trim to two channels so I just went with a matchbox....

I think you are mistaken, I link the trim for the mixed channel to the master channel with my 9Z.
