Creating a custom Date Slicer

Hi, Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

Test:

Calendar(a calculated table):

Calendar = CALENDAR(DATE(2015,1,1),DATE(2020,12,31))

There is no relationship between tables. You may create two measures as below.

DateRange = 
var _cam = SELECTEDVALUE('Table'[Marketing Campaign])
return
IF(
    ISFILTERED(Test[Marketing Campaign]),
    SWITCH(
        TRUE(),
        "Penetration" in DISTINCT(Test[Marketing Campaign])&&_cam = "Penetration",
        "1/1/18 to 5/25/2018",
        "BOGO" in DISTINCT(Test[Marketing Campaign])&&_cam = "BOGO",
        "5/26/18 to 7/4/18",
        "Contracted Deals" in DISTINCT(Test[Marketing Campaign])&&_cam = "Contracted Deals",
        "7/5/18 to 10/15/18",
        BLANK()
    )
)

Visual Control = 
var _date = SELECTEDVALUE('Calendar'[Date])
return
IF(
    ISFILTERED(Test[Marketing Campaign]),
    IF(
        HASONEVALUE(Test[Marketing Campaign]),
        SWITCH(
            SELECTEDVALUE(Test[Marketing Campaign]),
            "Penetration",
            IF(
                _date>=DATE(2018,1,1)&&
                _date<=DATE(2018,5,25),
                1,0
            ),
            "BOGO",
            IF(
                _date>=DATE(2018,5,26)&&
                _date<=DATE(2018,7,4),
                1,0
            ),
            "Contracted Deals",
            IF(
                _date>=DATE(2018,7,5)&&
                _date<=DATE(2018,10,15),
                1,0
            )
        ),
        0
    ),
    0
)

Finally you need to put 'Visual Control' measure in the corresponding visual level filter to filter out the result.
