How to exclude certain file types or paths from recently used files (“Recent”)?

In order not to clutter the list of my recently used files, e. g. when looking through a bunch of media files, I’d like to exclude some file types or paths from being included in the file history (e. g. exclude all .jpg files, or, if that’s not possible, at least exclude individual paths like ~/Pictures or ~/Music to have a similar effect).

I know that the list of recently used files is stored in ~/.local/share/recently-used.xbel, but how can I configure what is written there? The only relevant option seems to be in “Settings → Privacy → File History & Trash”, where file history can be disabled entirely. However, I still want to have a file history, just with some more configuration. I remember that, for example, in the Unity days, it was possible to exclude certain file types (like “Images”, “Videos” or “Documents”) from being tracked in this way – did this functionality disappear?
