I have the option to block users, but do I have a way of following or highlighting them in discussions?

I know that each user gets an RSS feed, but is there a way of using this within lemmy, similar to how I can click on "Subscribed" for communities?

The closest I have is this UBlockOrigin rule:

## e.g. highlight users: "tetris11" "kambusha" "Macniel"
## 
lemmy.ml##a[href*="tetris11"],a[href*="kambusha"],a[href*="Macniel"]:style(background-color: yellow !important; outline: 2px solid red !important;)

Which seems to work, but it's very cumbersome to write out rules like that
