Rest API play one song option

Hi all, Im using Volumio to play some specific sounds with the api, and would like to request ( if it is not too much to ask ) to be able to play one song and stop afterwards. ( I dont want it going to another song in the playlist afterwards )

Another thing is the ability to choose a playlist without playing it ( so I can than use the play_N command to play a specific song in the playlist )

In alternative was to add an option to play a specific file ( using path ).

Thank you!

Nevermind, the replace and play works great for this, and it is necessary to send the uri
