Page add bookmarks: create them automatically?

[ottogal]

Users having a role of "editor" are not able to add new entries to the list of Page add bookmarks (introduced in PW 2.6.17).

In my use case, there are several "album" pages containing gallery pages as their children.

Editor users are allowed not only to create a new gallery page within an existing album, but also to create a new album page.

When a new album page is created, I want to have automatically added a bookmark to it in the Page add bookmarks list, to let him easily add galleries to that album.

I think I need some sort of Hook to achieve this (but never used Hooks before).

Any help gladly appreciated.
