Collections on Xbox 360 App?

I don’t see a way to filter a library by Collection (specifically) or other filters in the Xbox 360 Plex App. Is there a way to do this currently – and if so, how – and if not, will this functionality be added to the Xbox 360 Plex App anytime soon? Also, are there any current workarounds that are being used until the functionality is added? Thanks in advance for any information that is provided!
