Support for Negative number fields for custom insights

We have several fields we bring over into Staircase for license use. One of these is Month over Month change. This could be a positive number (they are using 50% more) or a negative number (they are using -50% less).

Although I was able to add an insight for license growth over 25%, I was not able to add a license decrease for less than -25 (this would always show 0 customers). For now I added an insight for less than 0, but ideally would like to use a negative number as less than 0 will only show a decrease than since last month where less than -25 would show a more significant decrease.

In my case this is for license use, but I think you will find many numeric fields may have a negative and the ability to build insights on those negative values would be very helpful.
