Randomizing BluOS playlist with Albums from a streaming Service

I have a Bluesound Vault 2i. I created a BluOS playlist from several albums in my library. I am able to randomize all the songs, no problem. If I add an album (or albums) from my streaming service “Qobuz” to this BluOS playlist, the songs from these albums cannot be randomized and integrated among the songs from my library. They remain at the bottom of the playlist as whole albums, no matter how I randomize the playlist. Is it possible to randomize these songs from Qobuz within the playlist?
