Set Effect Props of Multiple Layers?

I have a group of objects and I want to set the glow size on all of them to the same value.

I see that I can filter for 'outer glow: size', but can I then set all the values at the same time?

Alternately, can I connect these values to the x position of a null object?

Thanks.
