Range slider step 0.5?

Hey,

I am using the slider filter for an attribute, and the convert to numbers option (available with Pro version), to convert string values to numbers so they work in the slider. Some of the attributes have a 0.5 decimal, like 4.5, 5.5, 8.5 etc, so i would like the range slider to work with 0.5 step, not whole numbers. I could not find an option for this or a way to override the code.

Is this possible somehow in the settings or with some code?

Thanks in advance,
Viktor
