Yes, In the Sop Import/Scene Import LOP there is a section for importing these called Subset Groups, you can select it manually of just put an expression like '*' to bring everything in.
Yes I am aware of the subset Groups in the sop import.
But I want to avoid subsets because they store indices of faces by primitives, wich is overkill for what I want. USD collection is what I need but I have no idea how to set it up from SOP to get nicely in LOPS.
