Feature Suggestion: Different Backend Mode for Each Games

[ismhael]

I don't know if this is the right place to post this. But this is my suggestion or maybe a request feature.
Is it possible to set different Backend modes for different games? I mean now, when you use OpenGL, all of your games uses OpenGL. And when you set it to Direct3D9, you have to restart PPSSPP to apply the settings to all the games. What I would like to suggest is using different Backend mode for each games. For example; I want my GVGNP to use Direct3D9 Backend, then on Dissidia 012 I want it to be on OpenGL Backend without having to restart PPSSPP over and over everytime I change my Backend settings. Is it possible?
