Work with ies file like dialux

It would be great if we can work with line leds and other forms like dialux. For example if i add a ies file from circle led it will be circle, not spotlight. and same for line very necessary, cause work with linelights in d5 render unreal. I’m working like lighting engineer and useful and comfortable work with leds. Thank you.
Also i want to tell you about video material. i dont know, but in reflection i see video and no lighting effect, only image, for example if i want count light in cinema with big monitor i cant do this or dont know how?
