Is there a way to add this?
Yes. It's not the easiest thing in the world, but it's not impossible.
More relevant: Is it worth it?
The answer to that is probably no. The software this site is running on is now in maintenance mode, meaning it'll get bugfixes and critical new features. Beyond that, I need to be spending my time developing QPixel into Codidact - see this Codidact forum post for some background on what's happening with that.
In the hopefully-not-too-distant future, we'll transition this site to Codidact proper, and there won't be any reputation in the first place, which will make this fairly moot.
Sorry that's not the answer you wanted!
