Add channels: edit normal and diffuse simultaneously?
Is it possible, perhaps by adding extra channels, to edit the normal map and the diffuse map simultaneously?

For example, let's say I have a collection of "stamps" that have both a diffuse and a normal. And I want to place these stamps all over my texture at various angles, scales, and positions. Sometimes I'll be using masks to control how the stamps overlap each other, etc.

The problem is, if I just have the diffuse and the normal open as separate images and try to make identical stamps on each, I won't be able to get them in the same position on both images. If they aren't in *exactly* the same spots then it will look terrible in game.

So, I tried adding 4 extra channels to my image, correspond to the nR nG nB nA, but I can't figure out how to copy the data from the separate Normal image into the appropriate channels. And I'm not sure if it will behave as intended once I do.

Does anyone know how to do this / if it's possible?
