Is there any way, when combining Commander's Choice with Random Classes, to allow the player to choose their option first, and then make the random picks?

This would allow you to select a primary or secondary weapon you want, either for fitting a background or filling a roster gap, and then having RPGO build a class around it. Whereas the way it is now you are likely to have a redundant specialization because you wanted a GREMLIN user and it gave you a holotargeter specialization, or you needed a sniper and it gave you a cannon spec.
