Add songs to 'Up Next' from smart playlist

Hello Everybody, Apple staff,

I really like the concept of 'Up Next', but I'm not able to add a song to the queue when I am currently viewing it inside a smart playlist.

The little arrow icon doesn't list this option, drag and drop to the top of iTunes doesn't work either.

The fact that I'm able to perform aforementioned action with a song that is viewed inside of a regualr playlist, makes me think that this is not a bug but a missing feature.

My workaround usually is to search for the title and use the little arrow icon to add the song to 'Up Next'.

The current behaviour breaks consistency and decreases usability, please add the option to add a song that is currently viewed inside of a smart playlist.
