Drivelist for FREESP

Just discovered this tool and it works perfectly. Thanks!

Is it possible to add an drivelist option to the FREESP as well? I see that the TSR has it. 

Or maybe it's a bug? If I run "FREESP.COM CD" it will only do it for the C: drive not the D: drive as well. Of course I can run it multiple times but would be nice to have it in one command line.
