That looks good, Steve. Maybe you could fabricate a simple, long block to rest against the wall, fitted so the outer edge is at a fence distance from the wall. You could add toggle clamps on top of it to act as stops for repeat cuts, or a screwed-down block in a movable T-track.. Use the block sort of like an outrigger bench hook idea, to move along the wall whatever distance from the cutting table you need. Store it away when not needed.
