I believe the answer is “no”, but I hope to be wrong.
Whether a Roon rep or developer in the know … once I use node-roon-api-browse (or other?) to find a song from my local library (I don’t stream) that matches an Artist and Song Title, is there a follow-up method I can call to add that item to an existing Playlist? (just to be pedantic, I’m not looking to create Playlists thru the Roon API. Only to add Songs that I have in my local library to a Playlist that already exists in my Roon instance.)
I haven’t dug in to all APIs too thoroughly. But I have perused most of them. I don’t believe I found a method to accomplish the above. Would be happy to learn otherwise tho. Much thanx to all replies in the know.
