For cabinetry a universal hold down system really is the best way on machines like this.

If you did go the pod route you'd have to locate the pods in VCarve/Aspire, and then use the coordinates to drive your machine to where each pod will need to be for that particular job and move the pod there. You could make this work (I've done similar jigs before) but the only way it's going to be worth it is if you're running hundreds of the same part.

Cabinetry typically has lots of different parts that are large, and that's where the universal vac system is really great.
