Greetings!
There is a website pixiv.net On it, you can add various works of art to your public bookmarks.
Also, during editing, there is a function with which you can select these bookmarks and make them private.
So, can someone write a script so that when you add a new bookmark, it is immediately added/transferred to private bookmarks?

Sorry for my English.

choose an image

adding an image

result (should be added to private bookmarks)
