Add group management for bookmark

Hello,
I’m looking to adding group management for bookmark.
Is it possible to mask/show some bookmark for specific group or at least roles ?
Thank’s

The bookmarks don’t have any user management. But you can change the side menu in almost any way. While doing this, you can access roles and groups to create specific menus.
See http://thruk.org/documentation/menu.html#make-item-available-for-some-groups-only for an example.
