Richard, unfortunate as it is, that is how it is. GBCI does insist that we use their forms, even when it's a big pain. The only good thing is that USGBC is working to develop tools that will make this easier in the future.
Richard, I would also contact GBCI about this, since it's a practical issue with their forms, and since their rep gave you permission for this originally. They might be responsive to a request related to this.
