Add a single dirt effect to multiple texture sets?

[King Mango]

I have a project with six different texture sets and now I want to start adding some dirt. Is it possible to have a master dirt effect that is universally applied to all the texture sets?
Is it also possible to have it only apply to five of the six while leaving say; the emissive channel, alone?

ok just figured it out. I made a new layer for dirt in my first texture set then I noticed right clicking on layers has an option to "instantiate across texture sets..."
ahhhh yeah
