That's fair.
If they could cross-link properly, you could have it formally in the options menu, so it's there if people go there looking to find it specifically, but also have a subtle and unobtrusive little check-box in one corner of the actual die-rolling ui for itself, shortened animations, that cross-informs the options menu tag and vice-versa.
And I really hope they fix their faulty logic that falls over itself and skips steps if you skip dialogue or animations.. that's just... it's just shocking, to be honest. Like, high school coding bad....
