Audio Behaviours in Motion -> FCP?

Hey all,
Not seeming like this is possible, but thought I'd check. I've built a template in Motion 5 where the background's behavior (analog modulator) is triggered by the audio in the piece. Is there a way to publish this parameter for FCP X so that the SOURCE AUDIO parameter can be changed as needed (in FCP X)? It seems like most of the other behavior parameters can be published, but I can't seem to get that one to work. Any ideas? Or any other thoughts on how to achieve this (or a similar) result?
Thanks in advance-
J

I've tried to do stuff like this too. My biggest hopes were on dragging the "Effect Source" drop zone from a Motion effect template into the "Source Audio" input for an "Audio" parameter behaviour, but it never worked.

I've requested it to happen, it could be a great thing.
