Provide a link to the portal URL for an idea in the agent interface

A common use case for my team is this:

1. I'm in the agent interface (/agent/object/[idea])

2. I want to share a link to the feedback portal URL for an idea with a user that doesn't have access to the agent interface e.g. /topic/[idea]

As it stands I don't see a way to quickly grab a link to the portal URL - I have navigate out to the public portal to get it. Would be great if there were a link directly in the agent interface, perhaps next to the title of the idea.
