It's more convenient to add availability to calendars by range. Instead of having to add all special availability one by one, as is currently the case, add it directly by range. For example: March 15th to March 29th, availability from 8 a.m. to 5 p.m. March 29th to April 12th, availability from 11 a.m. to 7 p.m. As is already the case with Calendly.
