VTX settings and support improvement. Changing existed Params description

Hi all, I’m trying to improve VTX setup and configuration to make it more easy and wide range of VTX to support without changing main code.
Now I compile separate AP version for each VTX used, it’s some slow and confused after VTX changing.
I can’t understand 1 thing- how to change config parameter description for MP?
Lock like I do correect, but in MP I see old descriptions only and new added params w/o desc at all.

In SITL (runned from VSC via WSL) I have absolutely abnormal Bands list

Nowere in my local repo I have these bands. But my own bands names not changed in MP after I connect real drone.

So next question- how I can use SITL for modelling VTX settings changing?

// @Param: BAND
// @DisplayName: Video Transmitter Band
// @Description: Video Transmitter Band
// @User: Standard
// @Values: 0:Band A,1:Band B,2:Band E,3:Band F,4:Band R,5:Band H,6:Band L,7:Band U,8:Band O,9:Band X,10:1G3 Band A,11:1G3 Band B
AP_GROUPINFO(“BAND”, 4, AP_VideoTX, _band, 0),

I can’t find answer in WIKI “Adding new params”

@rmackay9 , @peterbarker , maybe you can help?

Thanks.
