AutoCad :: Count Furniture Blocks In Specific Rooms

I need a way to count furniture blocks that are located in specific ROOMS. More specifically, I'm looking for a way to select MULTIPLE different blocks at once (with a WINDOW selection) and label them a specific room number. I don't want every block with the same properties universally updated (since some will be in other rooms). I also don't want to have to select each block in every room and update its attributes manually (this would both take a long time and things may be re-located over time).

I would like to be able to print a report and compare it to our Microsoft Access database. I know there are other furniture-CAD programs that will do this, but is AutoCAD capable of doing this on its own? I have millions of square feet to check furniture for and this would save me days- if not weeks of time!
