You could look at changing the Template to use Bus Follows instead -- just an idea to look into.
In the Auto Follows menu (Personality - More - Auto Follows) enable for CC, Panel and Editor.
Now setup Auto Follows that will send PST Bus Selections of the MLE to the Keyer of the MLE. Note that if your using PST bus selections for other elements beside this use you will have an issue here.
