Is there a product options app that works with subscription apps or vice versa?

My store is trying to sell a "Scone of the Month" box subscription and I am really struggling to figure out how to set up custom product options that will correctly connect an add-on cost to a subscription. The product flow I want is this: Base subscription box price is $12. Customer chooses if they want the specialty scone, sweet, or both (+$12) in their box. Customer selects if they want to add any curd, vinaigrette, tea, additional scones, or additional sweets. If the customer selected an add-on category, they then choose which flavor(s) they want from that category and how many of each flavor (with between two and 22 flavors available depending on which category). Each add-on adds cost, so, for example, if they want one jar of curd and two additional sweets it would be +$13 +$12 +$12. Customer checks yes/no about if they have any allergies and, if yes, there is a required box for them to fill out so we can give them an alternative if the regular monthly item has their allergen in it. All this information is captured, including the add-on costs, and hooked to a subscription. This box isn't available as a single order, it has to be ordered via a subscription. -- I was easily able to set up the options in both Infinite Options and Easify Custom Product Options, but, as far as I can tell, neither of them can correctly connect the add-on costs to a subscription - you can fill out the options, it'll tell you the cost on the product page, but when you click the subscription button to add to the cart it will always only show the base price. Is there a solution to this? Apps that play well together? A reasonably priced dev who can make options with add-on cost work with subscription apps? I'm incredibly frustrated and just want this to work. (Shop info - currently about ~$400-$500/month from online sales, most of our sales are in person but we're trying to get some steady online sales which is why we're trying to push a subscription box. Currently using Seal subscriptions but are willing to switch - our main like for Seal is the ability to increase the subscription discount every X months someone remains subscribed.)
