Courses and course formats

Hi everyone,

I'm new to Moodle and hoping there is a setting or plugin for my use case. I'm setting up an online intensive outpatient program for addiction recovery. The "courses" include 6 daily exercises each week (1 day off). That means that:

1. The "student" should start to have access to the first course immediately after registering. They cannot be scheduled to start on a certain day like an educational semester.
   
2. They should have access to each day's activities the morning after they complete the previous day, but not before. Also, since there is a rest day, the next week's 6 activities once they complete the previous week.
