Not on the CRJ. You can setup an advisory GS, but it's not precise or regulatory and cannot be coupled. The best you can do is calculate the vertical rate from the FAF, set that in VS at the marker, and hope it works out. It usually does, if your math is right, the winds are as expected, and you're very precise as to when/how you initiate the descent. High workload.
Better to do a coupled ILS in this situation.
