I just tried and it looks like I can do this in Chrome on Android relatively easily. The UI could be a lot nicer for it though.

And I did run into an issue where if the site allows me to install it as a PWA, Chrome will want to do that and won't want to bookmark a specific page on that site instead.

Also, maybe your point was that this could be done at the OS level rather than the browser, which is fair.
