I realized that after rereading the thread.
I had contacted CTC because I was curious about their Revit2Excel product. Their 2011 version does not include schedule keys though, which is essential to the GSA template, so he mentioned the collapse technique as a consolation prize. (the space type is a GSA key) Since I had nearly a thousand rooms to be designated type "01", I thought it was worth a look. Despite the missing schedule key feature, I still think it's a worthwhile product.
