Add to new playlist via selection from current playlist

[xnor]

Currently you can select a group of songs from your current playlist and, with the drop down menu, select 'add to playlist' and then select an existing playlist to add these songs to.

It would be nice if you could create a new playlist at this point and add the songs to this new playlist. Ideally, as per my previous feature request, this would not interrupt the current playback or modify the currently loaded playlist.
