Can lamps have more volumetric light control?

Currently it's all volumetric or no volumetric but with the option to adjust volumetric for different lamps it will also help in night/dark scenes

Start by locating the lamp-lighting and volumetric-rendering entry points in the Armory engine. Determine how the current all-or-nothing volumetric setting is applied and identify the existing rendering checks or tests, if any. Done means different lamps can independently control whether and how much volumetric light they produce, including in night or dark scenes.
