Channel Select Map for R-G-B-A

Is it possible to select the Red, Green, Blue or Alpha channel individually from a RGB(A) image? This is a widely used technique in game engines like Unreal, where a RGB(A) image is used for example to add scratches, wear, colors, material variations. In 3dsmax it is normally possible to do this with the color correction map by selecting 'custom' and settings all the channels to one specific channel. It would be handy for rendering game assets that already have RGB(A) maps without having to create individual grayscale images for each.

You may want to post this in the specific forum of the plugin you are using.
