What is reason Calendly does not yet support a recurring meeting option?

I am growing my coaching business and I really need to be able to book executive clients for a series 8 to 12 sessions upfront. Asking them to do this themselves is becoming too burdensome on my very busy leadership clients. I feel unprofessional trying to answer why the service I use for booking doesn’t allow this feature while others do.  

I see a post on running this through Zapier but, in addition to the cumbersome 20+ steps and testing laid out in that post, I would lose the benefits of reminder emails/texts to these busy clients.

I am considering moving my scheduling to another platform before my business grows any larger. I’ve found posts 2+ years old from Calendly saying this is a known issue and they’re working on it, but there’s still no built-in solution. 

What exactly is the hold-up? What aspect of integrating a recurrence feature makes this so difficult to implement? As a former product manager, understanding this will allow me to be more understanding and patient with Calendly. I’ve been very happy with Calendly otherwise but this is a major gap.

Thank you.
