The way My Position works is that you use the manual controls to move the drapes (or shades) to a desired favorite position and then push the stop button on the control to stop motion. Then, push and hold hold the Stop button in until the drapes (or shades) “jog”, indicating that the favorite position had been memorized. From then on, if the drapes (shades) are moving and a Stop is received, the drapes (shades) will stop, as usual. However, if the drapes (shades) are not moving and a Stop command is received, the drapes (shades) move from wherever they are to that favorite position previously set.
In short, the Stop serves both functions - there is no “move to my favorite position” command.
Hope that helps.
