Trying to add same song multiple times to a playlist

I frequently create playlists using my iPhone. I used to be able to add the same song multiple times to a playlist; I would choose the song and click the + to add it, then click the + again to add the song as many times as needed. I would get the message asking if I really want to add it again and would just confirm. Now I have to click “Done” and start over for each time I want to add the song — so much more cumbersome. Is there an easier way that I don’t know of! Thanks
