Something that would be a neat feature for the Calendlys / Cals of the world:
Some sort of "coupon code"-like feature where, if you want to allow a schedule override you can. e.g. if you normally schedule in CST (US) and need someone to have availability in Europe, you can give them a coupon-override to get earlier in the morning, or perhaps even a weekend (context dependent) to accommodate, rather than have your usual calendar avail just start at 5 AM on the regular.
