How to use PackageLinks for product/asset based items?

A little bit of context, I create ROBLOX assets and sell them online to customers, but a major problem I get is that for some of my projects, I use modules to help my code such as TopbarPlus to create UI, however obviously these modules update from time-to-time and break often therefore I’ve been looking into PackageLinks to create ease for my customers and contain less scripts within my product files.

Would there be a way for a single script to obtain these modules and require them instead of having the customer place the module within their game?

I know of stuff like require(12345678) but it would mean having to overwrite a model file.

If you know a better way around this, please let me know!
