No, for the consoles SL 32SX and SL 32SC the manual "StudioLive_Series_III_Studio_One_DAW_Control_Addendum_EN_V3_25032019" says in section "3.3 Fat Channel Controls":
"Please note: Because of their unique Fixed Mode Fat Channel design, this functionality is not available for the StudioLive 32SX and StudioLive 32SC."
The "old" SL16 does have this functionality.
