HELP! Steam libary categories for several computers

Seeking help from some steam pros who hopefully have a suggestion to solve my problem!

I'm using steam on several computers. 4 at the moment, to be exact.
Now I recently got a few more games and the alphabetical order of them in my libary is just not clear enough for me anymore.
I want my games to be sorted differently and yay- there's a great way to do exactly what I want to! Set categories to your games.
So I sat down and sorted all my games into the categories I wanted them to be in and was happy.

One hour later, upon loggin into steam on another device all categories were gone again and all games back in one big alphabetical pile.
I googled for a way to solve this problem, but all I found was old forum postings saying you have to copy certain files from one computer to another after every change you make in your libary.

Now my question is: is there any way to set steam categories accountbound instead of devicebound?

I really want to use the category feature, but if I actually need to copy around one file to all other devices everytime I log into steam on a computer that's not my own computer /or if I have to override that one file on my own computer everyday so I have the categories at one device at least - I think I'd be digging through my data folders more than I'm actually playing the neatly organized games.
