Mark as Complete Button on Onboarding & Training Add-On

We're just getting going using the Onboarding & Training add-on, and some of our initial user feedback was that the testers would have liked the "Mark As Complete" button to also appear on the Training Unit page so that once they were done reviewing all the associated processes/videos/documentation/external links, they could just click the button and be done vs going back to My Dashboard > My Training and click "Mark As Complete".
