PBI Matrix with sub columns - how to have conditional formatting per column?

Hi!  I have the data files but don't know how to upload them.  

I have data that looks like this where each row is a unit (# 1 - 3) , when it left inventory and how long it was in inventory, and what subtype of unit it is (Type A or Type B). 

This data is pivoted in Excel to produce a table where you can easily see the aging in inventory of each type across time.

 If I try to duplicate this in PBI I can get everything to work except for the conditional formatting.  

In the Excel table the conditional formatting gradiant is done per column.  But if I try to format the matrix as specified above, it does a gradiant for every cell.  Is there a way do have each sub column (the Type column and the total columns) be indepent in it's formatting?  This is what PBI does by default:

Note that in the real data I'll probally use a calculated column to show 2018Q1, 2023Q2, etc for every row.  

Thanks!
