I just use an old copy of burst that automatically selects all, thanks to CAB showing me how to do it.
Placed it into my support directory. The only reason is I can retain some objects like fixtures etc... while removing bound blocks of entire rooms. I just set the number of times to run the routine depnding on how nested the XREF's were before binding when I setup the background files.
