Support editing bonus successes from an attack before rolling damage.

Is your feature request related to a problem? Please describe.
Our GM does not allow bonus successes from brawl attacks to count towards damage, furthermore if an opponent dodges we have the same issue where either we have to edit the modifier to account for the reduced bonus successes, or use macros and not use the sheet for these attacks.

Describe the solution you'd like
I think making the bonus successes an editable field would save us a lot of time.
