category grouping

Hello, here I would like to share an option that I am sorely lacking on my discordant server.
I have a gaming server, but each game has its own category with a text channel and one or more voices, which is a lot of channels you can imagine.
I would like if it's possible to add the possibility to gather several of my categories in a single theme category.
For example, I have 6 categories for 6 fishing games, and I would like to make a single Fishing category where I would put them all together.
I hope this is understandable enough and that this option will appear in a future patch , please we need this.
Thank you for your help
