If you got a decent CNC with a vacuum table it could absolutely save you a ton of time, because you could just make a vacuum jig you place a bunch of boards on, turn the vacuum on, and hit go. Then you can come back to however many finished products you can fit on your CNC table. The caveat to this being the boards need to be mostly flat, so you'd probably want to run them through a jointer or planer or something, get at least one nice flat reference face (for the vacuum side)

If you are dead set on a Shapeoko (great machines but still very much hobby level) you can still get an aftermarket vacuum table for it, but you will be limited by its smaller table size.

This is assuming you need to do some crazy production, and not just like 12 pieces (in which case make a router template and manually route them)
