Find observations I've reviewed but did not ID

The title says it all really. I want to re-review all the observations that I’ve already reviewed but didn’t suggest an ID for. There are things I know now that I didn’t when I first started reviewing. So if there are any observations I’ve previously reviewed that still need an ID, I’d like to look at them again.

Finding all my previous reviews is easy enough. But I’ve looked at quite a lot of search url parameters, and I can’t see to how to do the other part. What I want is something like &without_ident_user_id=mine. Or really just any way to explicitly exclude every observation where I’ve already suggested an ID.
