List all scmVersions of an artifact since the start of the review

I'm writing a script to extract information out of Collaborator. The user manual has a command 'ccollab admin review-xml' for this. I can only find the last 2 scmVersions of an artifact from the xml file. Additionally I cannot find the date when the review started (there is a date when the review was created). The user manual describes some other ways to extract data but not very detailed. Can anyone help me with this or tell me where to find the docuements about this?
