How do I access the 1 button combos?

Feels very incomplete.

They have Paladin's Fight or Flight changing into Goring Blade, but Requiescat doesn't change into Confiteor. The latter making more sense than the former.

Unless I'm missing an option to allow me to, but I don't see one.

Right now, it looks like it's only FoF turning into GB. That one does make sense to me now, though, since GB is now only usable when you've activated FoF. I could see Req turning into Conf naturally, too, though.
