Add categories for your Steam games
Steam Categories
I can not upload new updates to this app due to changes in the policies of the Microsoft Store, they block me every update as the app depends on having Steam installed (policy 10.2.4). Because of this block, I can not keep the app updated, but you are free to take the source code and do with it whatever you want.

The app to work needs to know the location of Steam and load the information of each game (it may take time if you have hundreds or thousands of games)
If you select for example the Tag Assassin the app will select all the games that have that Tag, or if you select a game with 85% reviews, the app will select all games between 80% and 89%


And it only remains to return to Steam, you can return to the app to add more categories or delete all if you want to clean
