Right now in the scheduling module a provider's week can be set up to have different in/out-of-office hours and appointment type availability throughout that week. However, it doesn't allow for flexiblity between weeks or if there is a single day that's changed. For example, if Monday is usually an office day and Tuesday is usually and out of office day, if there's a week where the provider is moving their schedule to Tuesday, this isn't possible without some careful work arounds, blocks in the schedule, and remembering to manually change the entire template back.
