How can I make a Shadow Layer with Opacity Maps for Plants

My scene have a lot of plants in it, and each of them has their opacity map, I want to make a Shadow Layer to decrease the render time by rendering the non animated objects of the scene in a single frame. The Shadow Matte shader doesn't seem to accept an opacity map like AiStandardSurface, so the shadows doesn't work as they need to. How can I solve this?

Maybe Render Selection to Texture would work?

I don't think so... but I don't know If I understand how it would work.

I need this alpha to apply the opacity as a regular material to be able to compose it later because know It's losing shadows. alpha1.PNGalpha2.PNG
