It is worth noting that you can achieve this if you call out your dice separately. So !(5D10) becomes !(1D10), !(1D10), !(1D10), !(1D10), !(1D10).
That being said, I would also support this and would ask that it contain support for success counts, fumble counts, etc.
I have a character sheet built for a 2D20 system. I really don’t like the way that the system won’t show the dice rolls (except on mouse over) and only shows the successes/fumbles, so I have the sheet set to show all dice rolls and color the results to indicate the critical success/success/failure/fumble nature of the roll. This does become a problem with control over the number of dice. (It’s a lot harder to have the same calculation roll 3 dice this time and 5 dice next time when each die roll is coded separately and Astral’s coding language doesn’t support for-loops.) I can definitely see that this request would provide a solution for this.
Long and short, yes please.
