Ability to filter/view Issues upon "Versions" across multiple "Projects"

Greetings from Berlin, Germany!

Our JIRA-Deployment contains 4 "Projects" which have the same "Version"-Structure and Release/Rollout-Dates.
Currently, in order to have an Overview of Issues mapped to a certain "Version", we have to open each "Project"-Overview (Roadmap) separetely and check the involved Issues per "Project"....

It is currently not possible, to have an immediate and full Overview concerning all the Issues scheduled to a certain "Version" across multiple Projects sharing the same "Versions"-Structure.
This is a big Handycap for our Workflow, as we have to open 4 Roadmaps of 4 different Projects in order to make a Statement concerning the Status of a onstanding (or already released) Version.

Moreover, the Issue Navigator does not allow us to search/filter for "Fix Version" across all Projects - this is only possible for one Project at a time...

The lack of this "Feature" makes our daily JIRA-Work cumbersome, and it would be great if you could/would implement the Possibilty to fetch the "Version"-Information across multiple Projects as well as a possibility to search/filter for Versions across multiple Projects in Issue Navigator as soon as possible...

Thanx in Advance,

Cheers,

Alexander
