I'm a long-time subscriber but also an old-school player who enjoys rolling real dice. However, my fiance is joining us and I'd like her to try using the digital dice to help simplify her math until she gets the hang of it. I know how to roll for an attack and damage, but there are often still modifiers that I can't figure out how to add in. Example:

Adding the 1D8 for a Cleric's Divine Strike.

Adding the bonus damage a Barbarian gets for melee weapons while Raging.

The bonus damage from Great Weapon Master or Sharpshooter.

Is there a way to add these into the digital dice automatically or should I just build her a cheat-sheet?

Thanks in advance.

Extras like that will not roll automatically by default. But there are ways to achieve the effects to make it easier.
