[App_rpt-users] Decode two PL tones

I'd like my repeater to be able to decode two different PL tones. For no special reason other than my repeater used to be on the air under a different PL tone. I've changed the PL tone to be in line with other repeaters. I thought it would be nice for people running old commercial gear to not have to get their x9000s programed right away. Is anyone doing this? If so could you provide me and example of how it's laid out in your conf.
