LayerList Widget: grouped layers expanded by default?

Question

I've founding using grouped layers is a great way to save time since all of the layers come through as symbolized in the MXD.

Anyone know if there is a way in Developer to set the grouped layers to be expanded by default?

Thanks,

Derrick
