Exclude types of pastes on Mac/iOS (like color/hex codes etc) and exclude apps too on iOS

excluding types of pastes like i said in the title. on ios, when i copy a 2fa code, it shows up as a color/hex code. it clogs up my interface and i have to manually delete. also when i copy a file or photo or whatever on mac, i don't need that in my paste, so it would be great to be able to ignore certain filetypes or strings and not just ignore entire apps.
