I need to be able to create a custom view but then apply this view so that it is listed across all projects.  At the moment the most I think I can do is make it public which is only scoped to the single project that the custom view is created in, not all projects.

Hi Jason,

there is a high voted feature request already covering that topic:

Please add your vote and comments there if you want to add something to the specification.
