Yes, it would be great if there was a separate parameter for the top/bottom overlay.
For now, I’ll experiment with either a.) using a 1/2″ overlay and manually changing the doors/drawer fronts height or b.) using a 3″ wide mid rail and 1 1/4″ wide bottom rail and manually changing the rail widths. I’m not sure which would be easier/quicker at this point.
I may take you up on that phone conversation but I want to work through this current project design a little further to see if I come up with any other issues for which I need help. What hours are you available for a phone call?
