Dave here's one way to do it so the tabs line up for both side A360
All it is duplicating the first setup with it's toolpaths then flipping the Z axis in the setup and moving the bottom height to stock bottom for all toolpaths and changing the 2D profile back outside.
I added the patchies to allow the adaptive to cut down to the faces on the first side and the sketch for the 2D profile toolpath so you can guarantee the tabs are going to line up on the second side.
How to have the flip and line up done that's up to you but I would have the stock modeled and drill a couple of holes in it and use one of the holes for the WCS for both setups this works well as long as the holes a straight.
