Managing libl for multiple 3rd party products

I'm re-evaluating my management of libl for some 3rd party products.
Currently, I have the products that are widely used in the QSYSLIBL.
I recently had a RDB40 upgrade fail because it was calling INSTALLC with 2 parameters, but found INSTALLC from DBU10 expecting 1 parameter.
It took a week with Prodata support till the issue was discovered, easy fix.
Prodata is fixing their RDB40 install process.

Prodata support is suggesting using PRD lib. I've had issues with this with AJS and BRMS, they both use PRD.
IBM documentation states you can have up to 2 PRD libs, but haven't seen that happen.
Anyone have success with using PRD lib for managing a product libl?
I could add all these products to over 100 jobds, but I prefer not going that route.
Has anyone found some new magic on managing the libl for multiple 3rd party products?

Thank You
