OS Refinement, add the ability to attach related products to products, as it was in MVP

Good afternoon, Now in the OS there is no concept of related products, but lists are used. But it is extremely inconvenient for users to use this tool either to view related ones or to add new ones. How much will it cost to make a tool for adding related products, similar to Analogues or as it is implemented in the MVP version. When there is a tab and through the search, you can attach related products to one product (which it is desirable to sell together), without creating any lists, but simply attach one product to another and easily view it if necessary. There are 2 topics with this discussion, but nowhere can we find out the cost and put it into operation - for us this is a very important tool, because. product groups have related products, and after switching to the OS, we lost the ability to quickly work with this tool.
