New Magic Sheet Object Attribute: "Lock to Target"

Frequently on my magic sheets I will map a button to an EOS Target.  Could be a channel, preset, group, or anything.  I'll then need to move the target.  It would be nice if I could do that without also having to re-target all the magic sheet object that reference the moved target.

As there is obvious use to the current behavior also.  I propose adding a toggleable mode to enable target tracking as needed.
