Adding a limit on pricing plans per service rather then group of services

I’m having trouble with
making pricing plans that allow limits on multiple different services. For example as a pilates studio i might want a pricing package to allow 2 private sessions and 2 classes per payment cycle

Working in
e.g. Wix Studio Editor,

What I’m trying to do
Allow limit per service, rather then bundle all services to a limit and have to manage it off system

What I’ve tried so far
Tried the options available and limited to the payment cycle but that allows 4 private sessions to be booked, rather then 2 privates and 2 classes per cycle
