Is their a way search my pixiv bookmarks by tags?

on Danbooru you have the option to ordfav: + tag and you can narrow down search results. on pixiv is their a way to search my bookmarks + tag? I have about 8000 bookmarks or 400 pages so finding a particular image could take awhile!

I don't tag my bookmarks when I save them so that's not a option.

Get good at coding/writing scripts and become familiar with the Pixiv API. That's the only way to filter them down without tagging them that I know of.
