Update bookmarks

I use bookmarks to keep track of webnovels I read.

It would be nice if there was an easy way to “update” a bookmark, replacing the bookmark to eg FunStory-Chapter 5 with the bookmark to FunStory-Chapter 7.
Currently the fastest way I’ve found of achieving this is to bookmark the tab with Ctrl-D (taking care to ensure the bookmark goes into my “Fiction” folder), then remove the old bookmark (which requires 3 mouse clicks because I’m using folders to organise my bookmarks).

Not the most urgent feature request, but it would be nice if it could be done.
