Hi Marina,
Have you considered using our Open Badges functionality?
There's an associated report source.
'Badges are able to be awarded by Totara Learn for the achievement of defined skills at a course and site levels. Badges are able to be displayed publicly displaying the details of the criteria and evidence they were awarded for as well as the organisation who awarded the badge. Badges are also able to be collected across a number of issuers and stored in an external backpack.
There are two categories of badges:
Site badges: Available to users site wide and related to the site wide activities, like finishing a set of courses.
Course badges: Available to users enrolled in the course and related to the activities that happen inside of this course.
The main differences between badge types are the available criteria and the location within the navigation menus.
Enabling Badges
Badges functionality can be completely disabled or enabled in Advanced features under Site administration. This feature is enabled by default. If you completely disable the badges feature after having issued some badges to site users, such badges will still be successfully verified by external backpacks.'

Hope this is useful,
cheers,
George.
