Inventory Widget: Range steps

Is it possible to add a equal number range? I'm selling square meters to business and i need the range to be from 4 - 24 with equal intervals. i.e 2-4-6-8-10-12-14-16-18-20-22-24

By default, this widget is not offering stepping options.

But as a fast workaround, you may use this CSS snippet:

select option:nth-child(even) {
  display: none;
}

This will hide the odd values, and will look something like this:
