User tags for channels

Hello. Straight to the point:
I really need custom tags for channels. well, or at least a classification by importance.
For example: I group channels by topic first. But among them there are those that release videos once a day or more often, and some once every one or two weeks, and in general they are a priority and I do not want to miss videos from them. It would be very convenient to be able to assign a tag to a channel, and then filter, showing only it, or hide something.
I don't really want to produce tons of profiles of the type: "Games fav, games medium, games trash, games temp, etc" for each topic, so it is quite possible to get confused and extremely inconvenient
