Expand Spotlight Cone Angle to 170 Degrees

[Monkey Frog Studio]

Currently, the 'Y' cone angle cannot be set any higher than 90 degrees. I suppose normally this would be fine. However, in another program, I can set the spotlight to 170 degrees and I find this beneficial in some cases. For example, when you have something that looks more like a rectangular fluorescent light on the ceiling, placing a point light beneath it doesn't really work because the bright points, especially on reflective surfaces, on walls, floor, and ceiling, look like it's from a point light. However, in another engine, I simulated the broader lighting of a fluorescent light by using a spotlight set to 170 degrees and placing it very near the 3D model of the fluorescent light box. The result was a fairly nice wash of light on walls and floor with none on the ceiling. 

Currently, with only 90 degrees, I get a wider spot on the floor and maybe the lower parts of the wall (depending on how wide the hall or room is) and this looks worse than a spotlight.

Thanks for your consideration.
