My question is why?
From my experiences with Effect Layers, and the experiences of other posters in these forums, is that they work best close to the track.
I restrict TurfFX to within 100m of the track, others keep them much closer. Unlike textures, Effect Layer assets have a built in LOD which makes them disappear from the screen fairly quickly so painting them right out to the edge of the furthest baseboard will be a waste of time (they won't be seen) and may actually affect system performance.
As to how you would paint them on the entire layout in one move, I don't know. I had a look in both Surveyor Classic and Surveyor 2.0 (which I am still "learning the ropes" so I may have missed the answer) and could find the option for painting in a selected and limited area but not the entire layout.
