In the Buffs Section, How do I replace Strength with Intellegence

I'm trying to, with one click of a buff, replace my Strength Score (and everything that uses it) with my Intelligence Score. I'm using the Pathfinder character sheet. So far I've been putting "-@{STR}+@{INT}" into the STR Calc (a) section... aaaaaaand it goes on an infinite loop, switching back and forth every few seconds. I'm playing a Witch who has Prehensile Hair (Su), and if my witch picks up an object, or strangles a bad guy with a CMB, or makes a melee attack with it... I want ALL of that to be using her Intelligence Score, because the strength for her Hair and the strength of her noodle arms are to totally different stats. I could be lazy and just add +6 to it... but it won't auto update if I... say... level up... or get a headband of smartymcsmartpants... Thanks!

"@{INT}-@{STR-base}" seems to work... anyone else have any ideas to make it more... elegant?

Hi, which sheet/system does this relate to? That information can really assist the community in being able to offer other solutions/ideas for your consideration. Thanks

Based on the question, I'm gonna say Pathfinder and the neceros sheet, in which case here's your answer: In the attacks tab, there are alternative attack and cmb areas. Set these to be intelligence based, and set them as the basis for your prehensile hair attacks.
