[Camera] More resolution options

Hello, I'm happy owner of Lumia 930 with Windows 8.1 .. Is there any way to get more resolution options under camera settings? There is only 5MP / 5MP + 16MP and 16MP DMG .. I know what you will say but I need anything above 5MP for example 8MP or 10 or 12 is there any app that will let me do that? or any registry tweak? Thank you. Downsampled 5MP is good but 8 or 10 would be even better.
