Shopify - Bold app customization

I want to using a bold app in Shopify. My store is [login to view URL] BACKGROUND I sell oranges but in 3 products I offer my customers a discount if they buy in advance (before the fruit is mature) a bigger than usual quantity. Oranges are ready in December each year so I feel this product (the discounted product) from February to November. Then, once the fruit is mature, I stop selling the promotional product it but I start the shipments of the fruit purchased this way. It is delivered in 4 different shipments spaced between 15 and 20 days each. It depends on weather factors so I cannot foresee any regular interval. At the same time, I sell the regular product but at the regular price (no discount). It is a different product in the product portfolio, this is just for info. It does not interfere with the promotional product. After the selling process of the promotional product is closed, I send 4 boxes in 2 months but I decide when and what it contains (although it is stated at the beginning, when the customer buys the product). Nothing is to be charged to the customer in this shipments as they have paid the full amount at the beginning. I have 3 different variants of this product. The promotional product are oranges, tangerines, oranges and tangerines and lemons. Sometimes, some customers want to have a different delivery date. Some customers also want to include more products of my portfolio paying for the extra product. WHAT DO I NEED? I want to use Bold Subscriptions app. .- I need to be able to generate the orders whenever I want, just clicking, not on a defined interval. this is, I want to trigged the app with a click or introducing a fixed date (i.e. tomorrow) instead of time interval (besides to be more precise, original intervals should be working at the same time for other products). .- I need the orders to be of a regular product but at a discretional price (typically 0€). Why is this: As I have 4 promotional products of this kind, giving each of them a different price allows me to sort them out and arrange shipments. .- I need to give the customer the opportunity to buy any product that they would like t be sent alongside and to be included in the order. I think this is a basic functionality f the bold app.
