Hi Karen,
Unfortunately there is not activity reporting aside from SCORM data available in the Report Builder. I recommend that you check with your Partner company to see if they have developed additional custom report sources to pull activity data.
Also, I know in the Zoola reporting analytics tool has reporting around activity time as well. Again that would be something to check with your Partner on to see if they deploy Zoola or another analytics tool to complement Totara's functionality.
Thanks!
