Female Defender of the Faith

I was doing a Orleans-France order of Saint Joan run, and after forming France I was doing the Crusader mission tree, when I realized you can't claim defender of the faith as a female ruler (I had it before, but then another nation claimed it, and I can't reclaim it). I feel like it kind of ruins the flavor for this run specifically. I understand why it's there, but I feel like for the order of saint Joan specifically there should be an exception.
