How can I rename a artifact container? When I rename the LPA then when I try to create a link between e.g. RDNG and RQM there will be a drop down list with the artifact container name to choose between and this name is still the old name - how can I change that?

I have read the answer to antoher question: Can I change an artifact container name? - and tryed the proposed change, but it doesn't help.  and I do not want to loose all the releations created between the artifacts in the different tools.
