if tags can be added to each subscription source？

Hello， I wonder if tags can be added to each subscription source？
Consider the following scenario: I can tag a certain subscription source with labels of type and degree of interest simultaneously. When I specifically want to read content of a certain type, I can use type. When I consider my time more，content with a high degree of interest can be read every day, and content with a low degree of interest can be read monthly. This can avoid the pressure caused by having to read all subscription sources.
What do you think of this application scenario? Thank you for listening to my suggestion.

And we can add tags such as "block retweets on Twitter" and "block likes on Twitter" to some subscription sources. Although it can also be achieved by customizing the title, it cannot be searched and classified, and it cannot be uniformly modified to other tag names if we need.
