Third party tools for peer review of exam questions

Good morning!

Is anyone using a third-party tool for peer-reviewing exam questions? More details on the scenario below:
A CME provider offers self-assessment exams every year. These exams have anywhere between 75 to 100 questions. They are exploring third-party tools that allow their education staff to peer review exam questions, capture feedback from the reviewers so that the exam questions are “approved” before they are added as quiz questions in EthosCE.

If anyone has heard of or is using third-party tools for accomplishing this workflow, please let us know.

Thanks for sharing your expertise, as always!
