Is there a way to use physical dice rolls and still use the auto calculations? Can the dice number be typed in or something in an action?
You would need to create a Stat on the character sheet where the user of the sheet can type in the dice roll, then edit all the actions to use that Stat instead of rolling.
At present Astral does not have a way to input a number in an Action.
