Documenting the RCX_Function change to SERVOx?

First thanks for adding the extra ch9-16 to the Gimbal setup page!
Second can you do the same for the new CH9-CH16 options on Extended Tuning page for Auxiliary Functions?

I am not sure when RCx_function was changed to SERVOx but I checked in the changelogs and can’t find it.

Are the options and numbers for RCx_function exactly the same for SERVOx?
Could someone update the Wiki to add the SERVOx Parameters?
Thanks a lot!!!
