@kiwiscott -- I use Qobuz through LMS (Logitech Media Server) and am able to easily build playlists that include albums without having to add track by track. It also integrates my local collection along with Qobuz material.
And, while I don't build many playlists on Qobuz directly, I was also able to do this through a web broswer at play.qobuz.com. I just experimented and had no problem quickly starting a Qobuz playlist and added several complete albums with just a few clicks. LMS can also use these playlists.
Not sure what problem you are having.
