Is it possible to mass 'reset' attempts for a group of learners that fail an assessment?

Summary:

We have a large number of learners and we use a lot of scorm content with assessments/tests. If we limit the number of attempts and a learner fails, we can reset the attempts one learner at a time. But due to the large number of learners it is not practical for us to do this on an individual basis.

Is it possible to mass 'reset' attempts for a group of learners?

Is it possible to set a 'lock-out' for a period of days/hours and then allow the learner to retry the assessment?

Please let me know how you are managing large numbers of learners - thanks.
