Allow CTA due dates to be based on calendar days (not only business days)

Gainsight can only set the "due date" for a CTA using business days. e.g. If the due date is "Rule Date + 30 days" it will add on 30 business days to the rule date, not 30 calendar days. This prevents me from creating CTAs where the true due date maps to an actual calendar date. For example, I thought an "easy win" to encourage adoption amongst our account managers would be to have a CTA fire 90 days before a renewal reminding them of the upcoming renewal, but this can't be done -- at least not with the proper "due date."
