Joint Can and Fatigue Analysis Chord/brace member

I understand that SACS automatically make the largest diameter member or thickest member(if they are the same diameter) to be the chord member at a joint can. Is there a way to force the largest diameter member as the brace member? BRCOVR only allows one to override the brace thickness but not the brace diameter. Would also like this to carry over to fatigue analysis. Thanks!
