Option for Legacy/Custom Controls in Forge mode

The forge mode in halo is very dear to me and I spend a lot of my hours on it. Halo 3 , Reach and 4 forge modes were brilliant. But when I got to halo 5, I was definitely astounded by how brilliant it was but I was underwhelmed and slightly disappointed about the control change. I know new features were added but could there be a custom controls setting were you could choose what button did what? It would be great since Halo infinite is coming on PC. Anyone else agree?
