How to limit purchase of isolated bottles to specific quantities?

Hi,
I just installed your plugin on my Woocommerce store, and I am about to buy the Pro Version, but before I would like to confirm with you that the features that I need are actually included:
– I will have two type of product categories on my store: subscription wine packs, and isolated wine bottles. Given that, I need to define a fixed quantity for isolated bottles, as I only have boxes of 1, 3 and 6 bottles. So, what I need is my cart to limit the purchase of bottle to 1, 3 or 6, but allowing at the same time to buy the subscription packs, on the same cart.
So, basically limit the wine bottle category to 1, 3 and 6 bottles on the cart, and the subscription category with no limit, on the same cart
Is it possible?
Thank you!!
