# Description
This PR adds a new table named `user_product_bundle_contains_services` in intermediate core.
Mainly, this table serves as a bridge between `user_product_bundle` and `product_services`. A `product_bundle` within `user_product_bundle` can contain 1 or several services, and this was stated in the field `contains_product_services`. The value of this field corresponds to the sum of `product_service_binary_tier` from the services that apply within that bundle. Even though the information is quite concise using this format, it adds extra complexity for analytical purposes, so this new table just duplicates the `user_product_bundle` main attributes as many times as services are contained.
For example:
`id_user_product_bundle` = 383 contains one unique bundle named Basic Program. This bundle has the `chosen_product_services` = 257, which can only be decomposed in power of 2 as of the sum of 256 + 1. This bundle therefore contains 2 services, Basic Screening (`product_service_binary_tier` = 1) and Waiver Pro (`product_service_binary_tier` = 256). Thus, in the new table, we will have 2 records and remove all this logic to something more standard, as seen in this screenshot:
