[5e OGL] Set stealth to use Disadvantage?

Hey, is there a way to add a code to the character sheet that makes a stealth roll use disadvantage for wearing heavy armor? I know we can set up a macro, but was hoping there was something we could add to the character sheet that would automatically do this when clicking stealth. Is there an API for this? We have quite a few new players and were hoping to make it as easy as possible. I don't think they would remember to hit the macro when roll for stealth instead of just clicking it on their sheet.

I can't see a way to set only the Stealth skill to disadvantage. So a macro is probably your best bet probably. You could make it a token action if that's easier for your player to remember. Another option would be to house rule that instead of disadvantage it's just a flat -5 or something and that's something you can easily do in the character sheet.
