Photoshop + 3D Painter combination

Hi!
Since Substance Painter came to 3d artists hands it has always been a desirable feature for every texture artist to have an ability of sending current work into Photoshop and get it back to Painter.
Why? -Because Photoshop has its unique brushing ecosystem which has became native and habital for many handpainting texture artists. 
So I assume 3d artists don't expect a full layers stack interoperability between Photoshop and Painter because functionality are too different. 
But if we could send to Photoshop and pick back some specific basic color layers, as a projection or as flat layers method, it would be super helpful and game-changing!
