Plex playlist download/sync

Hi! I’m an Infuse Pro User and have a quick question…

I have several smart playlists in plex that I watch in Infuse so I can adjust the playback speed. I’d like to sync them locally but I have the following problems:
I can’t download an entire playlist, I can only download individuals videos.
Once I download individual videos they’re just shoved at the top of the library view, rather than being in a folder or playlist.
Once I’ve watched them and I usually watch 10-15 at a time, I have to then go and manually delete them.

Is there a better system for my use case? Both Plex and Emby for iOS have the concept of ‘Download this group of content, keeping N on the device and deleting when viewed.’ Is there anything like that for Infuse?
