Mute Group modes in JJOS2XL

I'm on JJOS2XL v. 3.82 (MPC 1K, small screen). Can't find how to select mute group mode (for example, "exclusive solo"). When I press "Window" button while in track mute mode, ther is no such parameter.
Is it even possible? According to JJSOFT, this parameter exists in JJOS2XL, not only in jjos128SP.
