Princess, does Alice's android body physically manipulate the controls of the MAS? Or does Alice just plug directly into the unit?

I feel like, even if her body is sitting inside the machine, she shouldn't have to actually manipulate the control sticks to control the MAS. It'd be far more efficient for her to just assume control of the MAS like it was another body- it would make her effectiveness in combat a lot more pronounced too. Instead of having the arguably less precise method of essentially relaying orders to her android body to relay orders to the MAS body
