Facility Control

This is the command I think should work, but it doesn't: XPT MME:3:KEY:1:MME:1
This works: XPT MME:3:KEY:1:ME:1

I have tried many other syntax options but to no avail and the documentation I've found doesn't seem to cover this specifically. Does anyone know the proper format for this? I want MiniME3 Key 1 to have the output of MiniME1.

I believe the source is: MME:1:PGM with :PGM being required.
