Single classification upload to multiple variables

We use the SiteCatalyst video reporting system to track video playback across our network of sites, but it doesn't record everything we want about video.  We also record some performance metrics like buffering time and buffer underruns, so we have to record the video identifier as a prop and eVar.  To get the unique video identifier classified, this means we have to upload the same update files three times to get the video classifications, prop and eVar all classified.  The  processing at the Omniture end is done three times too.

What I'd like is to be able to link a single classification source to multiple variables, across multiple report suites.  The multiple report suites part is already there, but not the multiple variables.
