Painter Masks from Base Color

artician

TL;DR - When working in photoshop there are dozens of ways to use your brushstrokes as a mask of some sort.  Is there a way to do the same in Painter? 

I painted down some strokes on a model.  I didn't set up the brush to affect all channels at first.  Now I have a layer in Painter that affects the base color channel, but not metal/rough.  I want to apply the brushstrokes for the base color channel to metal and roughness. 

Can I create a mask from the color channel, or is there a setting to tell the existing brushstrokes to apply their pixels to the other channels on the material?

Thank you in advance!

I was able to achieve what I wanted by isolating the layer I needed, exporting out the textures, and reimporting it as a bitmap mask.  Worked great!  Is there a better way?
