Very interesting, did something similar, I made a "where are they" map, it had a grid over the office floor so had a big staff list Bigal lev 5, A 1. I used the phone number as a link to an image of each staff member, so their picture appeared on their desk I simply saved each staff image as the extension number. It was reasonably fast making the new dwg inserting around 100 photo's per floor we worked in a 5 story building.
