My question would be "Why?". I find that using the MDI and Jogging controls are more than adequate for simple jobs. No, I don't have an MPG, but that might be another option.
It also sounds like you don't have ballscrews on the the unit at work because they can be easily "back driven" and this could be a real pain if you were trying to do a manual job with them.
Just my .02 worth.
