GRE PSR-500

I plan on relocating to the Massachusetts Area soon. Massachusetts uses P25 Phase 1, and Motorola Type II Smart zone. All frequencies are i 800 Mhz using CONTROL and ALTERNATE 800 Mhz freqs. Can the PSR-500 program and use use just the control and alternate frequencies only without the other frequencies? Roughly, there are about 30 control, and as many alternate channels. Thanks for any help folks!
