choice of exporting occlusion_roughness_metallic_ or to keep our files

Another feature request :

The choice of exporting occlusion_roughness_metallic_ or to keep our files :

I get the optimization idea, but sometimes i need to puzzle-replace one texture by another and i’m a bit stuck because the texture is part of an exported occlusion_roughness_metallic_ map.

For ex : baked AO maps are often UVmap channel 2, but the iOS AR USDz scene can only manage one UVmap channel, so i have to replace AOmap with white.png when going to AR, then put back AO map on AR exit. Easy with my pngs, hard with occlusion_roughness_metallic_ maps.
