Tagging a single page in a document

I’m curious if it’s possible to tag or bookmark a single page within a PDF document, so that it can more easily be found again? (I see that this question was asked back in 2014, and the answer was “no”. I’m hoping that’s no longer the case, but I can’t figure out how to do so, if it is now possible.)

I think this post in effect answers your question in the negative.
