Room Number assignment

The Measure default is to assign a room number at the center of the room which unfortunately seems to be the default of every architect.  Now I understand that I can change the number location for each room manually, however, if I could change the Measure default to locate the number in the upper left for instance I could read the architect's number as well as the Measure.  This would eliminate the need to manually change every room number so the guys in the field can read the drawing.
