How to get the root documents and folders

So basically I want to get the root documents and root folders without getting both of them at the same request. By calling just the endpoint "/docfdr" I can get the documents and folders together. (I am not sure if this is a bug or a feature...) I know that I can filter the ones I want out, but the problem is that the request I send has also a $$LIMIT and that would affect both types (if there is also a possibility to limit just one type of them, then that would be ok too!) - In my case I only want to limit the documents of this request. Is there an endpoint or a solution for that? Thank you in advance!
