[Request] add in groups nesting for materials

It may be a small thing, but I would like to be able to nest groups when setting up materials, similar to how we can nest groups in blueprints.
Currently, I need to try and use naming conventions to organize the material instance parameters by doing things such as (1. material settings, 2. Albedo Settings, 2.1 fuzzy shading, 2.2 color manipulation, etc.)

It would be nice to organize variables in materials using the same methods we use in blueprints, such as (Albedo Settings | Fuzzy Shading, Albedo Settings | Color Manipulation, etc.)

Thank you.
