Turn assembly sketch into Layout

Is there a way to turn a sketch into a layout in an assembly?  I have finally learned one useful feature of a layout over a sketch.  I can create a moveable linkage that is still moveble from the assembly.  Sketches are frozen when you exit them.

Now I would like to take the geometry and relations I created in an assembly sketch and move it to a layout.  Is there a straightforward way to do that?

Thanks,

Marty
