I am building a react application where I will have Two Main Organisations ( for usecase ). Each user should be a host to create interviews with the members under that particular User. 

For Creating interviews, I need custom durations where I will have a form to enter date, start time and end time. After submitting this, Can this be sent to calendly to add the invitees under this organisation ( User ) and generate an interview.

Also I want to list interviews, Cancel and reschedule them, all should be one organisation Specific.

Is this possible in Calendly, if so what plan should I get and what steps Should I follow ?
