Pacing Evolve Course with LMS Course

Does anyone have experience with pacing an Evolve object with the structure of a course in an LMS? What I’d like my learner to do is follow the path within their LMS, come to an Evolve object as one of their objects, complete part of it and be redirected back to the LMS, move on with their path in the LMS and then come back to the Evolve object where they left off later. Two caveats are that I need this to be one Evolve object so that their answers to questions are captured together and I am using the footer navigation for them to progress from one screen to the next.
