Hanna, first.... thank you for the reply!
You are correct that Code Reviewer does not support server side triggers, however I am not using any of the CodeCollaborator triggers (these are things that code collaborator does automatically based on review actions). I am using the code collaborator command line tool to create reviews. This is a SVN trigger or hook, which uses the cmd line tool. For my example I am using the cmd line tool directly (no SVN triggers). Sorry if my initial description was confusing. I should have title it "create-review CMD always creates a new review with every svn checkin". I hope this clarificaiton helps.
