Surround Sound using soundtrack pro 3

Hi

Im trying to create a surround sound mix for a CGI video and i know how to alter the surround tab but what i want to know is there a way to key the tab so it moves because i has some cameras moving around the characters as they are talking and wanted to get the sound to follow them

Any help would be great

Andy

If no one knows could you point me in the direction of somwhere that might be able to help or is it not possible
