In the March issue of Woodsmith Magazine there is a tip in the front for just such a jig, although it's designed to be used on the TS and as such has one leg longer so that it rides in the miter gauge slot. You could do a quick adaptation of it by takeing some 3/4" ply and making an H with the cross bar just above the table. Then and another piece across the top that overhangs and becomes the pusher that also will hold the stock against the fence. The one they show has the top adjust able with a pair of knobs that ride in slots in the top and screw into the outer vertical piece. Being that this is to be used for routing operations, I'd also add a sacrificail backer board on the back end to help prevent blowout. Wish I had a pic I could send you.
