C90LE7 WFR3 Image and Multi-Touch Monitor

Hi, I am attempting to integrate a Planar Multi-Touch monitor with a C90LE7 WES 7 thin client using the Wyse WFR3 image. It appears that Wyse left the "Tablet PC" Windows features out of the WFR 3 image. I am therefore curious - what is the simplest way to add this Windows feature to Wyse's existing WFR3 image? Do I have to deconstruct the whole base image in Wyse Device Manager and re-package? Perhaps the WFR1 or WFR2 images included this feature and it may be easier to revert? Unfortunately this is on a single device so a solution with minimal effort would be appreciated. Thank you!
