User-created physical material presets

It would be fantastic if we could save and load custom presets to have in the physical material presets list for common starter materials.
The ones there are useful but having your own custom ones would be even better. Think of it as an alternative to a material library for base materials already set up how you like them.

what kind of base materials would you make apart from the one which are already present in the preset, corona material library and cosmos?

More plastics and ceramics would be good but thats not really why i think the feature could be useful. It would make consistency slightly quicker to achieve and also be a great timesaver.
 For instance im currently doing lots of work with a 'studded plastic brick company' and it would be great for storing presets that dont need maps, just specific SSS settings and colours from brand guidelines.
Its the same sort of reason id love to be able to load libraries into the corona colour map to be honest. It would just be great to have things like paint manufacturers, pantones and brand colours easily accessible within the material.
