Yes.  A rotating force doesn't have to be defined with the "Rotating Force" in Mechanical.  It can just be defined with a complex "Force" as shown below.  You can define as many complex forces as you want.  Note that to define a force rotating about Z in a positive sense (right hand rule) you have make the imaginary component negative.  You would think that a positive rotation would be positive X into positive Y, but it's not.
