Google+ recently added some amount of YouTube integration in the form of a fly-out widget which lets you create playlists off of YouTube search queries.
When sharing a video from one of those playlists, you get a nice big button in the post which allows your followers play the playlist directly in Google+:

This is all well and good if you just want to search for anything related to a keyword on YouTube, but YouTube has its own playlist functionality where you can individually specify what videos are added.
Is there a way to get the new playlist behavior on Google+ for pre-generated YouTube playlists?
