you can return an FX through a regular input channel. There you can insert another FX.
Not in front of my console at the moment, but the system block diagram shows “other rack FX” as possible input for any of the eight FXs.
Maybe that’s another solution?

to answer your question, No, FX short sends do not have insert points.
But If you use a regular aux send as an FX send ( which burns up one -or two if in stero- of your 20 mix busses), you’ll get an insert in a send bus ….
