Steam Workshop not syncing objects?

I have installed Wallpaper Engine on my permanent PC with 30 workshop objects subscribed to. Now I've bought a laptop and installed the wallpaper engine, but I have to download all the subscribed objects. How do I stop that? I only want the subscribed objects on my PC and only the objects that I have subscribed to on the laptop

As far as I know, this is not always downloaded automatically

That's stupid.

Unfortunately, the workshop is accessed with your Steam ACC not with the device ID

It would just be better if the object was downloaded and not subscribed to

Yes, I can understand there's a steam workshop downloader for manual download but I would very much doubt whether this is legal
