Enhanced input to take camera's boom relative rotation into account

I have a top-down game where a player can change the relative rotation of the camera boom to have a different angle. However, I am using wasd (keyboard) to move around. So, as you can imagine, when I rotate the camera like that and keep pressing W it will still go that same way and after you rotate 90 degrees it gets hard to remember which way you will go. How would you make W (going up) always go up relative to the camera boom’s relative rotation?
