Set AA Quality besides the other settings.

Hi, i want to know if it possible to manually set the Anti Aliasing quality level besides the selected quality level, for example: If I select Good Quality Level in my settings but I want to set AA to Enabled is that possible, obviously im talking about in-game settings, not editor, i know its possible in the editor if i set the preset to have AA enabled, but i want to be able to do it in code separately, how I need to do it if its possible. This is so far my code, i want to know if its good, before i develop any GUI for that. public static int[] LoadVideoSettings() { int[] settings = new int[2]; if(PlayerPrefs.HasKey("UnityGraphicsQuality")) currentVideoSetting = (PlayerPrefs.GetInt("UnityGraphicsQuality") >= 0 && PlayerPrefs.GetInt("UnityGraphicsQuality") = 0 && PlayerPrefs.GetInt("AALevel")
