Option to link the Github (Enterprise) and JIRA user account?

[Alexander Grimstad]

Hi! 

We've got a working DVCS Account between our Github Enterprise and JIRA Software. All GHE projects are synchronized and Smart Commits are enabled. 

Everything works fine, and commits and JIRA comments are presented correctly, but; in the Activity pane of a JIRA issue, the committing user is linked to the Github account, which, not the JIRA user account. 

Is there a option / feature to join these two, and chose if we wish to present it as a JIRA user by default? 

By doing this, we get gravatars and a more seamless integration for those of our JIRA users whom does not have a GHE account.
