Joe, while I see why you would hesitate, I feel like that would not happen if it was a checkbox you would willingly have to click (and you would probably need to have at least one divorce date in there?)
The problem with the biography idea is not knowing which date to use. For example, I have been working on sourcing and building out the profiles of Margaret Rutherfurd-69 and her husbands, siblings, and parents (excuse the work in progress on all of their pages!) The problem lies in the fact that that she went Mills, Dukes, Murat, Sprague, Sprague, Murat, meaning that Charles Murat was her 3rd and her 6th husband. Which date I choose changes the order, and it makes it kind of awkward to handle both in the profile fields and in the biography - which is why I haven't put ANY marriage dates in for any of them, even the ones she only married once. There's no policy for "use the earlier one" or "use the later one" or what.
