Dual KPI

Hi,

I have some sample data below : 

I want to compare Sale count with Previous month sale count for each type of my product

Based on comparision I have a column called Satisfied i.e if current sales > previous sales, value is true else false.

I want to show the True or false value on a KPI like a traiangle 

Eg for True I want to show an upward poitning triangle in green

For false I want to show downward poiting triangle in red.

I have checked out custom visuals but none are precise. Is there a workaround?
