Physics Material Is Needed

Good morning

I was playing about with the physics setup and was abit baffled as to why we cannot not have the physics material ? This has great uses in UEFN when using with physics ?

I can get access to a material albeit not create in uefn direct but anyways when i attach to a material it throws errors which is expected somewhat but i mean why can we not have this simple thing as part of the physics ?

Epic have a bunch of them ie snow, grass ect and i can apply them without an error but i then cannot change any of the values ?

Could we atleast get access to a default epic one so we can change some things or even let us create an instance of an epic one if possible.
