Multiple region render management Script Required....

Hi...

I am not a script writer.. i am looking to contribute through ideas.. I hope I can be of help as scriptspot has helped me and my work a lot. Thanks and thanks in advance.. :)

What I work with are high res renders - 4k 8k and so on and i have multiple machines...

I am looking for a script that will render multiple regions of a image...

What i am specifically looking for is

split scan lines of backburner but with the width and height option.

Autosave these regions with incremental save...

Much need.. asap..

Thanks :)
