How to derive stem wall to the align with sheathing on exterior wall

[nick66 1]

When creating my foundation I'm wanting it to automatically align1/2 an inch past the main framing layer for my OSB sheathing to sit on.  I've tried creating half-inch layer in my foundation wall defaults.  Below the concrete description there's an option for an offset.  Is this where you can change it?  If So I must be doing it wrong.

In the wall Type Definitions dbx, use Foundation to Exterior Of Layer to point to your OSB sheeting.

You can further offset the foundation out past the wall by using a negative value for Foundation Offset.

Nevermind I figured it out.  You have to go into your exterior wall defaults and select which layer the foundation is to build to
