That makes sense. Most buttons I have seen were indeed just blocks of wood with a rebate and a screw hole.
That is the way I used to do it, before I got the DF500. I just cut a groove down the entire length of the aprons, just like a drawer side, and a matching rabbet on the clips.
After that, I have used the 6mm Dominos, tight in the blocks, wide in the apron.
