Filtering the drop slicers

Hi dharish20240911 

Currently, the dax function can not recognize place names, and if you can't join the relationships, you can only manually add calculated columns, for example:

Here's a sample able:

Table3；

Add a calculated column:

Country =
SWITCH (
    TRUE (),
    'Table3'[City] IN { "Delhi", "Mumbai", "Hyderabad", "Chennai" }, "India",
    'Table3'[City] = "Beijing", "China",
    'Table3'[City] = "London", "Europe",
    BLANK ()
)

Best Regards
