Delivery Calendar with Product Swap & Lock-in Date Control

Here are the specific details and requirements for the delivery queue/calendar feature we are looking for: 1. 12-Month Visibility: > Inside the "Manage Subscriptions" portal, the customer should see a timeline or list of their upcoming 12 deliveries (e.g., March 2026, April 2026, May 2026...). 2. "Swap" or "Select" Functionality: > Next to each upcoming delivery month, there should be a button allowing the customer to choose their perfume for that specific month. When they click it, a popup or side drawer should open displaying our available perfume collection, allowing them to swap the default product for their preferred one. 3. Easy Queue Management: Customers should be able to map out their entire year at once. For example, they might pick "Perfume A" for April, "Perfume B" for May, and "Perfume C" for June in a single session. The system needs to save these choices and automatically trigger the correct product for each respective billing cycle. 4. Cut-off Dates (Optional but highly desired): It would be ideal if we could set a lock-in date. For example, preventing customers from changing their current month's perfume if the billing/shipping date is less than 3 days away. Ultimately, we want an experience similar to "build-a-box" or customized monthly clubs, where the customer has full control over their future product roadmap.
