Feature Request: Flats Calibration Wizard - Flatbox Brightness

Hi SGP guys

I love the flats generation wizard very cool - I like how it adjusts the exposure for the correct ADU and how I can set a min exposure of say 4 seconds. Vital for the HA filter on the ZWO 294MM

What I really need it to do is adjust my flatbox brightness automatically along side the exposure.

I use multiple sheets of paper to defuse the flatbox - so the algorithm could be start at say min exposure and adjust the flatbox brightness automatically to get close to the desired adu then adjust exposure
