I use a keyhole bit. They can be bought at HD or Lowes. I then set the depth of that keyhole carve depending on the board being used. Since the keyhole bit is not in Designer drop down list I just pick one on the list that I don't use very much and assign it as my Keyhole bit... just remember that. After that, you're all set. You'll start your projects carving the back first (keyhole bit) then it'll pause and have you "flip the board" and then run the project as you normally do. It works great for me and I use it all the time with my CW.
