My solution for attaching lanyard to bottom of camera
I attached the magnetic clip mount as usual. Then I turned the camera upside down and attached the lanyard to the bottom of the magnetic clip mount using a Black, 3 inch Reusable Rubberr Twist Tie. I can now wear the camera upside down and adjust the angle using the magnetic clip. I just slid the lanyard mount piece up out of the way.
