Completion Rules for ILT

Hi - I am having a challenge setting up a process for learners to enroll into and ILT that needs to be completed as part of a series. Here is the scenario (based on client need, not mine): Leaner needs to attend all 3 days to be complete. Normally I would create the session with 3 events, but the learner needs to be able to select what dates and locations work best for their schedule. So they could select Day one at location 1, and Day 2 at location 2, and Day 3 back at location 1. I tried setting sessions up, but you can only enroll into 1 session, not multiple. I created 3 different ILTs, created the variety of locations as sessions, then put the courses into a learning plan. This basically works, but is very confusing to the learner on how to enroll. You have to enroll to the LP, and then into each course. But once enrolled to the LP, the courses show the “launch” button which is not intuitive to the learner to click to finish the registration process. Is there an easier way to do this or an option to make it more obvious to the learner? As you know, they don’t tend to read instructions. Thanks.
