Landscape Streaming Proxy list via Landscape?

Hi all, I’m hoping someone can help shed some light on the data relationship between the landscape actor and its constituent steaming proxies. I’m wondering if it is possible to access the list of Landscape Streaming Proxies that live “under” the landscape actor even when they are not loaded in (outside world partition streaming distance). I have been looking at the included functions / variables in Partition Actors, various Landscape and Landscape Streaming Proxies and can’t find that list. Is it in the Landscape or World Partition Subsystem somewhere? Ideally I’d do this in BP but at this point I’m still just trying to map out the data flow. Any tips or guidance appreciated!
