Ability to enforce product selection limits per membership tier

We would like the ability to create membership tiers where customers can select a specific number of products from our catalog based on their tier, such as 2, 4, or 6 products per month for different plans. Each tier would have a flat monthly price, and the system should enforce the maximum number of products a customer can choose during checkout and on an ongoing basis. Additionally, customers should be able to swap or change their selected products each billing cycle while staying within their tier’s product limit. Having built-in logic to enforce these selection limits per tier would allow us to offer flexible, curated subscription experiences with clear boundaries. If this would be helpful for your store as well, please upvote this request!
