How do I z-zero a bit too large for the mounted z-zero plate?

I've got a PRS Alpha with tool changer. I'm trying to set up a 3" spoil board tool but it's larger than the pressure sensitive z-zero plate that's mounted on the tool rack. How do I z-zero the spoil board tool so that it's consistent with the other tools in the rack?

Can you manually zero to the table top
