Hi,
one nice addition to Bookmarks could be the possibility to add a current selection to an existing Bookmark, instead of having to select, modify the selections, create new and change names two times.
As an example it could be done by simply right clicking on to the filter in the selection bar or menu and selecting the relevant option or by using the already existing menu that manages the Select Excluded/Alternative options.
It would also complement the app/sheet Default bookmark when editing an already existing bookmark.
Thanks
