Appts+ & Membership integration

Hi
I am trying to use Appts + & Member Pro 2 to be able to allow people to buy recurring appointments in blocks.

Here is a list of the services
Discovery Session: 30 Min FREE

30 Minutes Results Session: $60
60 Minutes Results Session: $115
2 Sessions Per Month: $230
4 Sessions Per Month: $420.00
Monthly Group Session: $87.00

I have created two membership levels; 2 sessions & 4 sessions. How should I set this up so that the users can book the equivalent number of sessions in a month?

Thanks, Kyle
