Use Measure as a slicer without Unpivot Data

Hi everyone,

I have to re-create the sample view where % Expected Payments and % Expected Accounts are division calculations.

Slicer 1 : Month

Slicer 2: Division metrics - % Expected Payments and % Expected Accounts 

Slicer 3 & 4 : Company and Unit  

Graph : Line Chart with x axis as days, value as division calculations and legend as month

At present, I created another table like this:

In my data, I added two columns to hold this information and did unpivot.

I linked both the tables with the column Attribute and used the below DAX to do the calculations:

Measure = IF(CONTAINS(Table1,Table1[Attribute],"% Expected Payments"),DIVIDE(SUM(Table1[Payments]),SUM(Table1[Estimated Payments])),IF(CONTAINS(Table1,Table1[Attribute],"% Expected Accounts"),DIVIDE(SUM(Table1[Accounts]),SUM(Table1[Estimated Accounts])),0))

This solution works for me.

However,
I have millions of data and 30 attributes. This solution will increase my data rows to : Millions of Data * 30, which is a lot.
Every month, the data increases in size and I have to store that data in Power-BI Desktop.
Is there any way to achieve the same scenerio without doing the unpivot option in the actual data ? Maybe by creating different measure for each metric and proceeding somehow to get the correct calculation ?

Any help is appreciated.
