Multinet is not trunktrackable by today's scanners. That is to say, you cannot follow a single conversation as it hops from channel to channel unless they are the only traffic. I wouldn't bother to put the inputs in as you will not hear them in Torrington. Put in the 851-854 channels as you did in conventional mode. Since you are using the 996XT, you can take advantage of the temp lockout for the control channel unless it doesn't rotate.
There are also (3) 854.xxxx fireground channels that are repeated by vehicle repeaters on Ladder trucks.
Rebanded ITAC/ICALL (85x.x125 freqs) may be used seldomly but won't hurt to have them.
