Can we add our own links to the work item editor labels?

When we look at the work items in the editor, a few of the built-in attributes have a link on the label (like Tags, Owned By, and Planned For). These bring up different things (like OwnedBy brings up the owner's profile).

Is there a way to define our own links for labels that would bring up an external URL? For example, we have a specific attribute which we provide additional information for on a wiki page, we would like to make the label a URL link that would bring up that URL in a browser.

Is this possible?
