Woocommerce subscriptions / mix n match

Good afternoon
My client is a wine club, their site uses various woocommerce plugins to manage an online wine shop, membership, event bookings etc.
They wish to implement a members - only subscription to a bi-monthly wine case, where the members can choose the 12 bottles from the shop, or have them chosen by the club, and pay a flat bi-monthly subscription.

I see that there is a mix and match woocommerce plugin to handle the mixed case, but how can I make this product container into a subscribable product?

Any help here would be greatly appreciated.
