Playlists

[rjfriend]

I have 5 seperate playlists set up in my Spotify under "Your Music" - "Playlists" on my iPhone. I have an average of 300 songs in each of the 5 playlists totaling around 1,500 songs. I would like to make another Playlist that would include all of my songs that I already have in each of my 5 playlists under this new single Playlist. Is there a way to transfer my songs "in bulk" to the newly created playlist? Or do I have to transfer each song one at a time into the new playlist? Any help would be appreciated!
