Setting quality setting to custom through code should be less painful

https://forum.unity.com/threads/cant-see-changes-on-depthoffield.1437040/
"Bug" comes from this forum post and the idea would be to be able to have something like

dof.quality.value = (int)ScalableSettingLevelParameter.Level.Custom;

Instead of relying on using (int) directly since ScalableSettingLevelParameter doesn't really contain Custom, it's infered from the other properties IIRC

Also, it's not possible to override the Quality settings by code as well if you have your volume at runtime for exemple which creates problems

Maybe by adding an example to the doc in the runtime page as well.
