(Help) Changing Medicine check to a intelligence roll.

Hello, One of my players is playing a doctor, a non canon class of character. and in this class its says its medicine rolls needs to be on intelligence in stead of  wisdom. can I change this in the Roll20 sheet somehow? or is there a bether way to keep track of it?  Sorry for the spelling errors, english is not my first lenguage.

You do this but altering the proficiency flag will reset the roll, and I don't know if it survives level ups. It does survive whisper toggles at least. In the character sheet the medicine roll has an attribute (screenshot below) which you can alter with this: @{wtype}&{template:simple} {{rname=^{medicine-u}}} {{mod=[[@{intelligence_mod}+@{medicine_prof}]]}} {{r1=[[@{d20}+[[@{intelligence_mod}+@{medicine_prof}]][Mods]]]}} {{always=1}} {{r2=[[@{d20}+[[@{intelligence_mod}+@{medicine_prof}]][Mods]]]}} {{global=@{global_skill_mod}}} @{charname_output} The highlighted field is the section you would copy paste the above macro into.

Thanks, it worked, also thank you for the info where to put it. I'm new to doing this stuf. 

No problem!
