No such feature exists yet on the desktop version, but I am sure it's on the wishlist already. Apps might be able to implement this themselves, but I can't say whether any have yet.
If it isn't, OP should add it to the issues tracker! Adding things there gives the project leads, plus anyone who is willing to volunteer some time, to know what features people are asking for, and to choose some ready made things right off of the shelf to work on.
The devs have always been pretty helpful and responsive on Lemmy. I imagine that has changed a lot in the last few weeks, but they're basically always checking the issues tracker.
