frequency template for 450b and 450 SMs

I want to make a template I can use for all of my SMs that will select all of the channels available to scan. If I make a file that selects all of the channels available on a 450b, it won't do anything on the older radios that wont' support 5.1/5.2. is there a way to apply a template that ADDS channels to the radio, instead of replacing? or a way to apply channels to a radio, and have it just ignore the channels it doesnt' support (while selecting the ones it does)?

I've used the following with good success...

        "smRadioConfig": {
            "powerUpMode": 0,
            "frequencyScanList": [
