Context Links should contain conversation attributes

Context links are great and we use the time.

It would be fantastic if they could be used to transport information from front into the linked system, most critically conversationID or messageID.

This could happen via an amended query string or via the referrer or any other simple means.

I would like to specify a placeholder / dynamic variable for conversationID in my link target and front automatically replaces the placeholder at time of user clicking on the link with the actual value.
