Hi,qqqqqwwwweeerrr ,thanks for your concern about this issue.

Your answer is excellent!
And I would like to share some additional solutions below.
Hello,mannequinxox .I am glad to help you.
According to your description, you want to implement a date slicer (when month is selected) with text type to filter out the data from the selected month of the current year to the current month of one year ago, for example, select January-2024,filter out the data from 2023/1/1 - 2024/1/31.
If I understand correctly, I recommend you to use measure to customize the filter range.
Here are the test results.

It should be noted that since the slicer's filter field type is text type, power BI can not directly through the text type of the field to achieve continuous filtering. So my approach is to let the slicer to provide filtering date values, the text value into the correct date range, and ultimately through the custom date parameter range of the data tagged to display the last year's data (including the current selection of the month)
Here's my test data :

I created a separate slicer form for the slicer field

M_result2 = 
VAR MonthYear = SELECTEDVALUE('slicer_2'[DateMonth])
VAR Month = SWITCH(
    TRUE(),
    CONTAINSSTRING(MonthYear, "January"), 1,
    CONTAINSSTRING(MonthYear, "February"), 2,
    CONTAINSSTRING(MonthYear, "March"), 3,
    CONTAINSSTRING(MonthYear, "April"), 4,
    CONTAINSSTRING(MonthYear, "May"), 5,
    CONTAINSSTRING(MonthYear, "June"), 6,
    CONTAINSSTRING(MonthYear, "July"), 7,
    CONTAINSSTRING(MonthYear, "August"), 8,
    CONTAINSSTRING(MonthYear, "September"), 9,
    CONTAINSSTRING(MonthYear, "October"), 10,
    CONTAINSSTRING(MonthYear, "November"), 11,
    CONTAINSSTRING(MonthYear, "December"), 12
)
VAR Year = VALUE(RIGHT(MonthYear, 4))
VAR _selectDate= DATE(Year, Month, 1)
VAR _tableDate=MAX('Table'[Date])
VAR _startDate=EOMONTH(_selectDate,-13)+1
VAR _endDate=EOMONTH(_selectDate,0)
// _startDate:Returns the beginning of the month one year before the selected date
// _endDate:Returns the last day of the selected date
RETURN
IF(_tableDate>=_startDate && _tableDate<=_endDate,1,0)

The data is eventually filtered by M_result2:

I have also found other issues that have similar needs and have been resolved, so I hope this helps.
