If recurring training, then branch to test-out option

Okay heroes, I haven't figured out how to do this, and at this point I'm just wondering if it's possible.

I'm working with a Cornerstone LMS. We've got a recurring (Storyline) training module that I am revising. In this updated 360 version, my intention is to provide a test-out option for those who have previously completed the course.

I don't want to ask the user if they are repeating the course. I want to pull this information from the LMS,  send it to a variable in my course, and use the variable to dictate if the user can branch to the test-out option.

Possible?
