PCONVO duplicate error


is it not possible to have 2 different test sets with the same partial convo?

I am trying to start a test session through my test project, in which I put a couple of test sets. When I start the session it fails and I get this error:

Failed to retrieve test cases from XXX: Test Set compilation failed for Partial Convo script “PCONVO_YYY”: Duplicate partial convo: PCONVO_YYY
