Anyways to Use AO for Mass textures?

[Tag12345]

I currently use the Dirt Shader overlays onto a texture to use AO.

Thus requires making a mix texture in the materials of any texture i want to have AO, then reimport the original texture back in.


Wondering if anyone has found a way to use this AO cheat more seamlessly than using the Dirt shader for Each and every material xD


Thanks!

How I do it below for visual:
