Simple enough, the short answer is; if you qualify a welding procedure using a complete joint penetration groove weld, you are qualified to weld any prequalified groove detail listed in figures 3.12 (PJP) or 3.13 (CJP).
Again, the short answer is; if you have an overwhelming need to use a joint detail that does not comply with a joint (with applicable tolerances) shown in figures 3.3 or 3.4, all bets are off and you have to qualify the proposed joint detail to demonstrate the resulting weld meets all the test requirements stipulated by Clause 4 parts A and B.
