Rapid Rig: Modular V3

is there no Z up proxy orientation? we are using unreal and not being able to orient the proxy so i can rig/skin my model in that orientation rather than rotate it 90 degree and save for the other animator do do his work? maybe I am missing something? the other artist has his own version so he can animate with the RRM rig. just noticed that again maybe Im overlooking something. or should that even be a bother and just export as "z up axis" under axis conversion making this a nothing burger lol. also is it possible to add an option to orient the rig in Z up orientation, since we using unreal. so the other artists don't need to jump between Y up and Z up orientation in settings depending on what rig they are working on.
