gap at thick back dado

HI everyone,
Switching from Component to Foundation Library and trying to set up all our previous construction standards.
One thing with our fully dadoed thick back is the need for a gap between the tongue and sides/top/bottom for a little wiggle room; our case clamp squares everything up.
I cannot find that variable in Foundation Library.
Here's a picture with the gap in Component and the no gap in Foundation.
Thanks!
