This may be addressed elsewhere and in some capacity it is as dates relate specifically to project timelines which would be fantastic but it would also be great if we could have our request forms block out non-working days based on the account work schedule. Right now, users can select a deadline on a holiday or weekend when we have nobody on staff, even if we have it blocked as a non-working day in the account calendar. Sometimes I catch that error and can shift the project to align with our work schedule, but I have had instances where I didn't catch it. If there is a way to block this, I may have just missed it. If not - that's an essential add for us.
