If you are working to AWS D1.1 read 31 on the TAble 4.5, "except qualification of any CJP groove weld qualifies for any groove detail conforming with the rerquirements of 3.12 or 3.13" Essentially all your prequalified joint configurations can be used with that one Qualified procedure, at least that is the way I read it. Comments?
So joint configuration seems not to be such a big variable, most any joint would be able to meet the prequalified joint requirements, note I said most.
