LMS Commits and Timeouts

I am using Storyline 2

We are having issues with learners opening courses and then leaving them open for a long time and our LMS times out. The course is still open so the learners will come back and complete the course and assessment and Exit after passing the test. But because the LMS has logged them out due to inactivity the score is not passed to the LMS and they don't get a completion status. They then have to retake the course.

We are going to create a LMS timeout message that will display in the LMS if the session is getting ready to timeout to tell them to exit the course and relaunch it. 

Is this this automatic LMS commit something that is available in Storyline and if so can we add it to our courses?

Please help me in this query. 

Thank you in advance...
