How to render SSAO only for Movable Objects

Hi there,

In my Scene I use a stationary skylight. The Problem is, that I have some movable Objects in my Szene (like Barrels with Physics enabled) that are looking very bad compared to the static Objects with baked Skylight.

So I tried to use SSAO to make them look more realistic, but it effects also the static Objects with baked lighting and make them appear way too dark.

My Question: Can I apply SSAO only to these movable Objects, so my baked lighting doesnt get messed up?

(Static Fraction is doesnt work, as seen below, because the whole skylight is static)
