Tool for managing pbr trimsheet atlas?

What is the workflow and tools for managing PBR based trim sheet atlas?
Is photoshop and manual labor the current way to do it? 
It is pretty straight forward if you don't have lots of stuff but keeping complex high resolution atlas with all channels is very labor intensive.

Why would you do it in Photoshop?

I have always collected my pieces in photoshop and merged different channels as layers and then exported layers with channel names(albedo,metalrough, nomal etc)

So there is a better method?

Managing material channels like that in ps is a real nightmare. I know, I did it like that in the dark medieval ages. I'd lay them out all in a 3d software , bake base maps and masks and continue in Substance. Either Painter or Designer based on the requirements.
