2 default dates in slicer

lauriedata you should have a new column for default selection and use that as a slicer:

New Column for Slicer = 
VAR __Today = TODAY ()
VAR __Date = 'Calendar'[Date]
RETURN
SWITCH ( 
    TRUE (),
    __Date = __Today, "Current Date",
    __Date = __Today - 1, "Prev Date",
    __Date
)

Select "Current Date" and "Prev Date" in the slicer; these will be the default selection for every day, and users can pick one if required.
