-100 to 0 to 100

Some components works with 0 in the middle and -100 and 100 as extremes.
Example, now I'm working with Squash in the Scale component.
0 is the center.
-100 and 100 are the extremes.
It says to use an IntSlider or a Grayscale Control.
Better to forgot the Grayscale Control, because it only fits in special cases.
IntSlider can't be set as "-100 to 0 to 100". Only as "1 to 100".

Sorry to be critical, but I don't understand why there are many controls using the setting "-100 to 0 to 100" and no Slider set like this.
Yes, we can use an IntSlider to do the same thing with "1 to 100 to 200", but sometimes it doesn't seem to work well.
We can use Remapping.....

But...
...it would be useful to have a Slider with -100 to 100 settings.
( Value Control could be a good option, but FF doesn't accept it. It gives error, if we connect it ).

So....... the chances are :

1) I set the value of -88 as fixed value ( in my filter is not a good choice ).
The user can't customize it.

2) I accept a different look, not like I was thinking, and I give the chance to change it ( anyway the user will never be able to reach the result I got, except detaching the IntSlider and inserting the -88 value ).

?? It shouldn't tell you to use an IntSlider.

We've requested bipolar sliders before but we never got them.
