Track a window over an entire timeline?

I have cut up a short interview into many smaller clips to remove the 'ums' and 'ehs' from the interviewees answers. I now want to brighten up a portion of their face using a window tracked to their heads movements.
As all the clips are the same frame, a static shot of the person being interviewed, is there anyway to track the window over all of the clips and adjust it's settings from just one node?
Or do I have to apply the node to every clip individually and track the window on each one separately? There are 28 clips in total.
Thank you for your help.
