[QOL] Texture set channel templates

I would like there to be an easier way to set up channels for a texture set, as it can be quite tedious when working with materials and managing numerous user channels, especially for shaders external to Substance Painter, such as those used in stylized shading. My best idea would be something akin to export templates, but specifically for channels. It might even be possible to translate some of that template information directly into channels and potentially combine the two for a more streamlined workflow.

It’s possible that I’m unaware of an existing method to quickly set up user channels; if there is, please let me know, but I haven't found anything like that. My best guess is that, with a custom shader for Substance Painter, you might be able to define the channels from the start of the project.
