Export maps to Blender (NPR shading)

I mostly used Blender's texture painting before, and now I want to give substance painter a try. But I don't know how to export my maps to Blendre easily. I found that there is an official addon for Blender, but it only connects the PRB maps. What I'm doing is highly stylized NPR shading, for example I don't have a "Metalness" map, instead I want to hand paint the metallic glowing on a texture. The same goes for AO. Is it possible to paint these in Substance and easily export them to Blender? Or Substance isnt the right tool here?
