Apply global gradient to all layers - Flash

Is it possible to either:

  1. select multiple layers that contain shape tweened flat colour shapes (with outlines) and apply a gradient to all with one click?

  2. apply a mask that creates a global gradient to all the aforementioned layers?

Some more detail on the project:
Its a multilayered, shape tweening animation that I want to give a 3d effect by applying a gradient to each layer…the problem is i need the fastest way to do it as there isnt just one animation…there is about 70 of the blighters…

Cheers
