Separate an image input into channels?

Hello guys I'm wondering if this is currently possible to do inside of Octane? and if not would it be too difficult to implement this into a feature? thanks in advance.
PD: I mainly use the C4D plugin.

I am not sure if this works in your case, but I've used multiply nodes (in a group node with 1 input -> 3 outputs) to split R/G/B into individual textures nodes. You could then shift or scale hue/staturation with a CC node, before recombining them with an add node into a new texture, including swizzled channels.

It actually worked perfectly... Now I feel stupid for now seeing something so clear, basic math you input a matrix one side with different values then multiply two of them by 0 and you get a what's left on the other side.
Thank you very much! I will leave an image attached here with the process in case someone else gets here in the future.
