Additional Context Filter option eg "Version" & "Epic"

In the Planning Board - Assignee view the issues displayed are for the entire JIRA project (subject to any context filters).

In most cases I am only reviewing / working with issues for a specific version.

The context filter dialog does not contain "version" so to filter on version in the assignee view I have to creat a JIRA filter (project & version) and then use that in the context filter. Component is already a context filter option even though the Planning Board - Context view does this already.

It would be quicker if the version was a selectable option in the context filter perhaps only active in the views not otherwise filtered by version already.
