[ms office - 2010] Word page layout settings - chnage en masse?

[taff]

Anyone know how to change the page layout options in Word 2010 for a whole bunch of machines at once? Specifically, the default "Line Spacing" (of 1.15 back to single) and the "Spacing After" (from 10pt to 0). It's easy enough to do for a single machine and then change the normal.dot but I was hoping there'd be a group policy setting or even a registry hack for doing it to a room's worth of machines at once it and I can't find anything...
