Time lapse: Custom Auto ISO in shutter priorty (Tv) mode?

I want to do a 2-day timelapse series. it's indoors with outdoor light coming in from a window. I want to shoot at a fixed slow shutter speed around 1/6. I can do this part easily in Tv mode using the Ultra Intervalometer script.
My problem is that I also want the custom Auto ISO enabled in Tv mode and that doesn't seem to be an option. I want the AUTO ISO to help compensate for the day/night light variation.
Anyone got a way to enable the custom AUTO ISO in Tv mode? I can set the ISO to AUTO when in Tv mode, but it does not use the Custom AutoISO settings...it just uses the normal camera Auto ISo settings which seem to limit the rante between 80 and 200. I'd like to use a wider range like 50 - 800 so I need the custom AUTO ISO enabled.

I have a A590 and using  Mar 19 build.

Thanks,

Hi
Maybe you can try this script:  http://chdk.setepontos.com/index.php/topic,2156.0.html  not so easy but perfect for what you want.
(Can you just say me how to upgrade chdk... i just have to replace diskboot.bin et PS.FI2 (from autobuild server) onto the sd card? Maybe i have to do once again the complete installation, with a format of the card???  thx)
