With all these restrictions, you might as well use manual (auto iso or not)... I thought about this functionality and sounds great but becouse of how automatic or semiautomatic programs (same thing) work, it does not help.
Suppose you had this functionality:
You limit the speed to 1/125
Set ISO range: 80-1600
If the camera was choosing 1/30 before you set the limit, you "stole" two stops so now ISO has to increase two stops...
Now you point at a subjet where the camera would have chosen 1/30 speed but does not need those 2 extra ISO stops... the camera will default to 1/125 again...
It is how any automatic mode works..
I think my explanation is not the best but it works like that.
Try TAv and use ISO range and exposure compensation tu restrict the possible selections... that should be enough. You will realize you donīt have to tweak shutter speed that much
