Question/Suggestion for Move Tutor

Is there any chance, or is it even possible, to add an option to make the custom move a special move instead of a physical one? I ask this because I am currently planning a solo run with a Noivern or Gengar. Spending half your ev training on attack on a pokemon who specializes in special attack doesn't really make for a viable solo run and I just wondered if such a thing was possible or intentionally avoided.
