Method to assign IES file

[mgibeault]

I often have to to several tests to find the best IES file for a desired result. It can become very time consuming...
It would help me a lot if there was a command to assign an IES file to a light. I could then create a simple script like;

Select "Light 04"
SetIESfile "C:\Data\IESfile01.ies" <---hypothetical command
Render
SaveRenderWindow "Test_IESfile01.jpg"
SetIESfile "C:\Data\IESfile02.ies"
Render
SaveRenderWindow "Test_IESfile02.jpg"
SetIESfile "C:\Data\IESfile03.ies"
Render
SaveRenderWindow "Test_IESfile03.jpg"
Etc...

Thanks!
