possible to lock ISO in AEB - manual mode?

[spon]

Hi everyone. This is my first post (new P3P owner) and I have a question regarding the bracketing feature for photos. I come to this new hobby from a photography background (enthusiast, no pro) and am trying to get the best quality photos from my P3. Is there a way to lock ISO so that when you shoot 3 or 5 brackets using the AEB mode, only the shutter speed will change? I've noticed that while shooting AEB at dusk/night, the shutter speed will stay the same and the ISO will vary, even while in Manual mode with ISO set to 200. This results in multiple images that are basically the same, except for higher/lower noise.

thoughts or suggestions?

Thanks!
