With framing assemblies, the user can select the type of wires to be used in the assembly prior to placing.

Support assemblies allows us to create common guying assemblies (such as 2 guys to 1 anchor, 2 guys to 2 anchors, and 4 guys to 4 anchors for vertical construction). However, you can only specify the guy wire and anchor size when creating the assembly. While it is fairly painless to adjust the types after placing the assembly, it would be ideal to have dropdowns to preconfigure the assembly with a wire size and anchor prior to placement as can be done for framing assemblies.
