Chan_usbradio multiple tone decoding

In the conf for chan_usbradio, it shows you can have a list of tones to decode. For instance,
rxctcssfreqs = 77.0,94.8,123.0,131.8 ; RX CTCSS frequencies list in floating point. must be in table

Is there a function I can use to test which tone was decoded? example: 94.8 would return "2"
I have multiple repeater sites RF linked together, sending different PL tones so I can tell which one is active. I'm hoping to use chan_usbradio channel rather than an external community tone decoder. The system is also using Allstar linking.

As far as I know, nothing specifically to that effect.
But...
You can use tonemacro to create what you want. Roll your own LOL

A good workaround. I had used this method myself in the past but re-imagined other ways to get what I wanted 8 years ago. Should not have changed in v3
