Relative Date Slicer Week only

Hi derekmac 
The slicer cannot only choose the week, but maybe you can refer to the follwing solution to substitue it.

Sample data 

1.Create a number paramater to set it as last week slicer

2.Then create a measure

Measure = 
VAR a =
    SELECTEDVALUE ( Parameter[Parameter] )
VAR b =
    MAXX ( ALLSELECTED ( 'Table 2'[Date] ), [Date] ) - 7 * a + 1
RETURN
    IF (
        SELECTEDVALUE ( 'Table 2'[Date] ) >= b
            && SELECTEDVALUE ( 'Table 2'[Date] )
                <= MAXX ( ALLSELECTED ( 'Table 2'[Date] ), [Date] ),
        1,
        0
    )

3.Then you can create a visual and put the data to the visual, then put the measure to the visual filter(e.g table visual)

Output

Best Regards!
