Can you parent a Dissolve envelope?

[Archigram]

I have a complex hierarchy of objects that I'd like to dissolve en masse. Unfortunately it seems that dissolve percentage is not transmitted from parent to child, so I can't just apply the animation to a master null. I have to open a dissolve envelope for each object; then I can import them all into the Graph Editor, save the entire set of dissolve channels, and animate there, so it's not the end of the world.

But it would be nice to be able to do this in one step, if anyone knows a way.

Thanks!

My ShiftKeysPlus script comes with a script to set dissolves over a selection.

Yes-- this is it exactly-- thank you for addressing these issues.
