I'm not sure what you mean by "propogation" in this case. What are you wanting to propogate, and to where? Are you saying you want it to be inserted into every song in the entire library? Also, it's incredibly easy to just move a command after it's added, so I'm not sure I really see the value in adding a position setting that will just clutter up the dialog, which is more of a problem on smaller screens.
