Lightroom: Expand highlights and shadows range for 16bit floating point and 32bit images

When using "Merge to HDR" in Lightroom, the resulting 16 bit floating point DNG gets auto toned to be displayed as a useful exposure, where you can see the image (I'm not talking about the auto tonemap-option in the merge dialog itself!) You have (as you have with 32 bit Tiff) the possibility to set the exposure in a +-10 range, which is huge.
The problem is: as the image is sort of correctly exposed already, I find myself adjusting the exposure in a +-2 range at the most, because otherwise parts of the image go beyond the reach of the highlights and shadows sliders, leaving me with a very limited range in which I can manipulate my image. One could apply additional brushes to further change those regions (in the brush tool, the exposure slider is back to +-5 by the way!) but that is a bit cumbersome to maintain and fine-tune.

HDR files do have a huge dynamic range, and the whole (maybee not the whole, but you get the drift) point is to combine shadows with visible detail with highlight, also with visible detail. If the midtones are OK to start with, I need the extended slider range on the extremes of my histogram (ignoring whites and blacks for a moment) and not at the control shifting the whole histogram around.

So please, make Highlights and Shadows for HDR (16 bit float/32 bit) have a range of, say +-200, or convert these numbers to stops and let us have +- 5 stops for highlights and shadows individually.
