possibility specular and diffuse separating in Corona lights

Corona Corona for 3ds Max Feature Requests

is it possible to separate specular and diffuse lighting in Corona lights, especially in Corona Sun, for cleaner results with DOF and Motion blur effects in render with reflective materials.
for example: in some scenes with DOF effect no matter how many passes I will be rendered, a noise on speculars and highlights still remains, especially with exterior close-ups on a plants and other thick objects/Options of -/max Sample Intensity/ don’t help in this case, only if change the value of 1 or 2 - that is not a valid.
option -/Light Samples Multiplier affects only on Diffuse Direct Lighting, not specular//Also is no matter a property of glossiness of material itself/
I could never get a clean result in this case!!!

it would also be nice to do check box for overall ability to disable or enable refraction and reflection effects/

the option is already present in sun controls

we are not talking about visibility, we are talking about SPECULARITY option for light, same in VraySun/
Simply put
I need to lighting of the scene with Corona Sun does not depend on visibility of the Corona Sun

And i have another proposal.
whether it is possible to provide the ability to embed texture in Corona Sun just like it is done in the Corona Light/
thus it is possible to adjust the strength of the lighting scene, regardless of Sun visibility,and change its color and etc/
