Subscriptions – Custom Box Monthly

Hey there!

I am using WC Subscriptions and I would like to offer to my clients subscriptions plans that allow them to receive a custom box every month (for the custom box I am using the Custom Product Boxes plugin). Basically each month a customer can decide what to put in his monthly delivery by being subscribed to this service.

Is it possible to:
– make customers modify their product before their monthly delivery?
– modify the monthly order so that the products appear as decided by the customers rather than as the first they subscribed?

The first custom box is sold as a subscription so buying the same product would just activate the same subscription again. The custom product box should be modified each month within the subscription itself.

Thanks in advance!
