Move channels separately

[Vicente Bermúdez]

With Adobe Photoshop I have been doing 3D effects for a long time by moving the pixels of the red channel to one side and the blue ones to the other. It is very simple. But with Affinity Photo I can't do the same. Even if you select the RGB R or B channel, when I move them, all channels are moved. Do I do something wrong or does Affinity Photo not have that feature?
Thanks for your help.

Pedro has even made a Macro, so a simple click is all that's required after installing the macro.

Thank you very much, Firstdefence. That was exactly the effect I wanted to achieve. Tonight, when I return from the Halloween party, I will try to test the effect and create the macro to apply it. Nottingham is too far from Alicante, but take a beer and send me the bill.
