I just did this via the PSN Store on the browser. Put 10 items in the basket => buy => repeat until I had all the Season Pass DLC activated. When I booted up my PS4 everything showed up as installed under the related items section in the home menu.I don't know why they changed how the store deals with free/zero-rated DLC, Im sure before you could add it all to your basket and then checkout all of it (well max 10 items at a time) to purchase and batch download it.
Still a somewhat stupid system to handle things on Sony's side tbh.
