Input System custom Composite Part possible?

Is it possible to make your own custom Composite Parts?

The reason is that I do not like the naming convention for instance for 'Up' and 'Down' as they are assigned to the W and S keys of the keyboard. I would like to have 'Forward' and 'Backward' Composite Parts too, because in a 3D game they are usually what is meant instead of Up and Down. I might also for instance want terms as 'Pitch', 'Yaw, 'Roll' and such, and maybe even 'Yaw Left' and 'Yaw Right' etc...
