AutoCad :: Plotting From Single Layout Into Multiple Files?

I have floorplans from a building with a total of 80 appartments. Now i want to plot PDFs in A3 format, each page with 1 appartment. That would be 80 pages/PDF-files.

The way i did it up to now was i have put all A3 pages in a single layout and used the Window-function in the Plot dialog to print each page individually, manually numbering the file-names, and combining files in Acrobat as needed.

But doing this for 80 pages is too much - especially because i will likely have to plot it more often in the future. As far as i can see, i could make 80 layouts and use the Publish function, make a sheet-list and plot that way.

I keep wondering - is there not a more efficient solution to this problem than creating 80 layouts? There must be a more intelligent solution to this. Whats the preferred way of doing this?

P.S. i use AutoCAD2007 and Acrobat for plotting.
