Backgrounds with overlays for diff choices

[kinkiepinkie]

Hello, world.
I want to implement some player choices. Let's say, few clothes and hairstyles for few characters.
My game doesn't use png sprites of characters on still backgrounds. Every image is unique 'background' with characters rendered inside the environment.
I can make transparent png 'parts' of images with different clothes and hairstyles. To use them as overlapping sprites, acc. to players choices. But it's a hassle to ask engine if/else for every single image, since they are unique. Maybe there is some workaround?

How is it called? Some keywords to find a tutorial? Or even a link for an example?
Thank you.
