Help with customer self management for subscription orders

[wenybai]

Hello!

I am setting up a Shopify store for my prepared meal business and was wondering if there are any apps that would meet my needs for what I envision.

I would like to allow customers to customize their subscription through a build-a-box model and would like the following features:

-the ability for customers to freely add as many meals as they need to their "subscription box"

-checkout with the "subscription" as a single item with the individual meals that they have selected listed in the description

-the ability for customers to manage their subscription with options like pause/skip week/cancel

- the ability for customers to change their "subscription box" selections for the next order without the need to check out again (i.e they add 6 meals to their "subscription box" when they subscribe but want to change the number of meals for their next delivery or change which meals they selected to try something else)

Are these features possible to implement with any existing apps that aren't Bold Subscriptions or Recharge? I have somewhat managed to implement my first 2 points with bundle apps but need help with the subscription part and the customer order management. I've found a few subscription apps that allow customers to skip/cancel/pause their subscription but really would like to see if there's anything out there for my last point.

Any help or suggestions would be greatly appreciated!
