One answer
There is a request for this functionality: https://jazz.net/jazz/resource/itemName/com.ibm.team.workitem.WorkItem/117057
You can add your vote and/or a comment to this work item, if you need this functionality.
Note: Adding support for a new client is very expensive, because of the ongoing cost of adding and testing every new enhancement to that client.
