RTC 2.0.0.2 Can you reference an existing work item in a work item Template?

RTC 2.0.0.2 Can you reference an existing work item in a work item Template?
I have a work item template that relates the top level story with task children

<rtc_cm:com.ibm.team.workitem.linktype.parentworkitem.parent rdf:resource="#item0"/>

so when the template is invoked the tasks are children of the story (#item0)

Is there a way to relate a work item to an existing RTC work item? Such as:

<rtc_cm:com.ibm.team.workitem.linktype.relatedworkitem.related rdf:resource="https://jazzrtctest01.{myworkdomain}.com:9443/jazz/oslc/workitems/49096/rtc_cm:com.ibm.team.workitem.linktype.relatedworkitem.related"/>

I AM able to save templates locally, edit the XML definition, then replace the XML file through eclipse to update the template definition
thanks
