Mike,
You are right, and I currently do that now. I guess I thought that there may be a pathway to steer to the other talkgroups easily on my repeater in the future.
Currently I use a TG that is local to my repeater and goes out to my network of ASL repeaters.
If I really wanted to do I could change that BM TG.
