Assigning Lessons Myself

I'd really like to know if there is a way to "assign lessons" to myself, by myself. I previously have been on the "guided" lessons and I know that lessons can be "assigned" to me and "unassigned" so that they are more readily accessible. I can make a list of lessons myself and store it as a file etc but would love to be able to assign the lessons to myself so they appear in the mobile apps under "Assigned". It just would be much easier to manage currently studied lessons.
