Conviction Setting rule be added to the SWADE ruleset

Would like the character sheet to be able to show/track conviction. I think a checkbox on the Traits tab would be fine. Unchecking the box (using conviction) would roll 1d6, which can Ace as normal. The result would have to manually be added to the result of the previous Trait or damage roll because I don't think it is possible to have it automatically append a previous roll.
