D1.1 Multiple pre-qualified joints

I suppose, but why? It might be very confusing for the welder who is trying to use it.

I agree that it would be confusing to the welder and everyone else. I am reviewing Subcontractor's WPS. In order to reject the WPS I need somthing to quote from the code(D1.1) to prohibit this. To my dismay I have only found para. 3.6.1 which allows combination of qualified and prequalified WPS, but dosent specifically address joints.

I don't think you can reject a wps for that reason alone via the code.

AWS sells SWPS with multiple joint configurations, and some SWPS even stipulate that any prequalified joint may also be used as long as all other variables stay within bounds.

I think whether or not multiple joints are advisable on the WPS would depend on how the welders are trained, and how the shop in question prepares their drawings. As long as they have a system so that the welder can make the appropriate joint, it shouldn't be a problem. Code wise, the WPS can satisfy D1.1 with one or multiple joints listed on the WPS or even just a reference to another applicalbe joint document.
