More integration

I am new to substance designer but one of the things I've notice is is lack lateral integration with illustrator and photoshop. Specially the pen tool and masking features. I come from the 2D apparel graphic design world and trying to integrate 3D design into my work. I think it would be a great idea to either make the workflow from Pt to Ps and Ai easier or bring some of the power of those tools to Pt. I think the having a true pen tool like Ai and Ps would speed up my work faster in Pt. Also the having the ability to draw with pen tool on iv maps and seeing the updates in real time on the 3d viewport. Also if there was a way to texture the imported svg vector would be nice too. I've tried googling and YouTube to find the answers what I'm asking for and they don't directly exist. All of these apps should work hand and hand so much so that the workflow is seamless.
