NJSP programming revisited

Using a Uniden bcd436hp here. Monitoring NJSP is too broad and I'd like to narrow it down to a couple of key areas in their own favorites lists. I've always noticed I spend a significant amount of time scanning the various "IR" frequencies compared to the specific talk group ids. Also each NJSP group I add to a favorites list adds these IR freqs into the favorites list as well.



Are all of these necessary or can I trim this down and speed up scanning by a significant margin?
