Having the option to use Vigor in some spells

This is something that blaffes me that it works like this in the vanilla game. Since Swdteches and Blitzes are spells, the game uses the magic stat to calculate the damage they do. Therefore, slamming your sword against the enemy depends in your magic stat and not the more relevant Vigor.

During one of B-Run's streams he said that something like this could be done, and even assign which spell uses Vigor or which uses Magic with FF3usME, apparently the last row of ? checkboxes are empty and one could assign code to that checkbox?

Also, I remember on RotDS that Magitek's beams did more damage depending if you're on the front row. That would be a nice thing to implement for swordteches since it makes sense.
