Persisting Bookmarks

Is it possible to persist bookmarks? aka what is the intended lifetime/scope of workbench bookmarks?

This question stems from a chapter I am writing on sql tools. I have used the bookmark feature in the past and upon testing it I see that you can assign bookmarks to any editor and then save/close the file. Later on (so long as you have the same bookmark window open with the bookmarks set) you can reopen the file and the bookmark appears.

What I am trying to explain is how do your persist a bookmark beyond the setting in the bookmarks window? I want to store a bookmark with a sql/mdx etc file and not have to rely on it being set in the IDE. I want the bookmarks window to autopopulate upon opening of the corressponding file.

Thanks,

Derek

Bookmarks in Management Studio are consist with Visual Studio. To use bookmarks your files need to be part of a solution/project, rather than just loose files. Yes, the environment allows the creation of bookmarks on files that are not part of a solution but these bookmarks are not persisted. When you create a solution, add a file, create some bookmarks, the bookmarks will be persisted and show up each time the solution is opened.
