Packages - assign value to various services

[JubileeWellness]

I would love to use packages. However, I need an option to apply varying values to different services within a package. Can a feature be added so that on the package creation page I can assign a value to each individual service on the package? For example, I own a biohacking facility. I would like to be able to sell a package for 10 credits and have all my biohacking modalities included. However, when they use the hyperbaric chamber it deducts 3 "credits" from the package, when they use a sauna it deducts two "credits", when they use an energy device it deducts 1 "credit", all from the same 10 credit package. The feels like an easy thing to add and would really help business owners have options for selling and tracking packages
