Complicated Pivot Table Issue With SUMIF like logic.

This is a sample set of data:



Funding is cumulative throughout the year and not particular to one month. So if it is 2022-03 Funding is 20 for MGMT and not 15. The larger data set has multiple Units for same dates in different rows as shown in a few examples in the sample set. Now in the pivot table, unfiltered the values for funding are correct since they are overall sums of funding for entire time frame 01-12. If I filter by date I only return the funding for that month instead of a summation of every month before that as well. So If I pick 2022-04 from the date slicer My funding in the pivot table should be MGMT funding: 20 Power Funding: 95 and Sales Funding: 90 but instead I get MGMT: 0 POWER: 20 SALES funding: 80. Is there any way to calculate this in power query, power pivot, etc in order to get this type of field.
