Ability to edit the 'Epic Link' when creating or editing issue from issue view in JIRA

The new Greenhopper Rapid Board uses the 'Epic Link' field to relate a story to an Epic.

However, I like to directly edit the Epic while I am viewing a story in JIRA or edit it later on. Even I have add the 'Epic Link' to the create/edit issue screen. (As some users do not always edit stories in GH Rapid board only). Therefore It will be great if we can set or edit the Epic Link in the issue view page in JIRA.

At the same time, in the 'issue detail view' of Greenhopper Rapid board. You can delete the entry of the 'Epic Link' field in the detail view but cannot edit it, and you always have to go through drag and drop to the Epic.
