Filter by two dimension combinations - powerbi

Question

My (heavily simplified) data model contains of:
a fact table with FTE values and two foreign keys for 'Country' and 'Process'
two dimension tables for 'Country' and 'Process' with relationships to the fact table
I also have a table of combinations of 'Country' and 'Process' that I want to filter my data on:
Country Process Country-Process
= = = = = = = = = = = = = = = = = = = =
France process 1 France process 1
France process 2 France process 2
Australia process 1 Australia process 1
Australia process 3 Australia process 3
USA process 2 USA process 2
USA process 3 USA process 3
The goals is to filter my FTE, to show only FTE for these country-process combinations. However, it is not possible to have the Combinations table filter both Country and Process tables through relationships.
If I filter on Country, I get all processes for those countries. If I filter on Process, I get all countries for those processes. If I filter on these countries (there are more) and these processes (there are more), I get all these processes for all these countries. But I just want the combinations listed.
I have succeeded in making a measure with a SUMX on a virtual table that only contains the listed combinations (works in DAX Studio), but the Entity relationship somehow got lost and all countries showed the aggregated value per process.
The measure is set-up as follows:
SUMX(
FILTER(
CROSSJOIN(
ADDCOLUMS(
CROSSJOIN(VALUES(Country[country]), VALUES(Process[process]) ),
"Country_Process", Country[country] & " " & Process[process]
),
VALUES(Combination[Country-Process]
),
[Country_Process] = Combinations[Country-Process]
),
[FTE]
)
Help is much appreciated!

Assuming your tables and relationships look like this:

DAX Calculation:
You can use TREATAS to create a virtual relationship. The measure can be either a visual column or a filter in the table.
Filter FTE =
CALCULATE (
COUNTROWS ( FTE ),
TREATAS (
SUMMARIZE ( Combinations, Combinations[Country], Combinations[Process] ),
FTE[Country],
FTE[Process]
)
)
