Controller key binding/remapping LT+RT

First of all, giving controller support has truly been a great experience so far. Although there are somethings that could be better I'm very satisfied with the implementation.

The question I have is when you remap your controller buttons, I see that by pressing LT+RT together it brings up another set of empty buttons that could potentially be mapped. But I can't seem to remap these buttons by pressing the R3 button like the other buttons.
I ask because the archnemesis menu is mapped to LT+RT+X and I can definitely use these extra buttons for Auras and Relics.

Anybody find out how to remap them?

Thanks!

Same here just started playing, and use PS4 controller on PC. Found that I can use L2(LT) + R2(RT) but cannot seem to config any function.
Anyone have an answer?

Same issue here...

You can't remap them I think, because they are reserved for leaugue mechanic stuff (like temple map during Alva, or placing explosives during Expedition).

One tip though, if you scroll through your skills while assigning them with R3, you can just press square on your Auras to cast them without having to assign them.
That way you might not need all the buttons.
