Ability to check for / block specific product codes

> Hi @Dragon1573
> Unfortunately, each brand has its own package name (and we have more than 50 brands) with nothing in common, as the name is decided by the company selling our product. For example 3Kontakt, Tele2 Växel, Telia Touchpoint, ....
> So the only common point for these brands is the ProductId, which is shared. Is it possible to be add a filter on this level?
>
> [!NOTE]
> Regarding 3Kontact.3Kontact, there is even a typo in the name, as the name of the package should be 3Kontakt (with a 'k')

The issue names no files, tests, or entry points. First determine which project owns package filtering rather than manifest data, then clarify how a shared ProductId should be represented and matched across brands. Done would mean an agreed, implemented way to block or filter packages by ProductId.
