Choose default value for slicer (Single Select) ,but show other available values

[Alex_G7]

I have 2 slicers (Year month in French) + and Start week .

"Start  and End of the month "defined  by acccounting    so  for example first week of February starts on 2021/01/31....

          

I want on each  opening of  report  set   Month Year  slicer to Max  Value -1 (in March 2021 ,it should be February 2021) and Week start slicer to Last week of February (2021/02/21 )

Leaving user option to change Month Year  and Week start later 

Thank you

New column "Month Type"  will have following presenation in "single selection" Slicer 

"This Month"

"Last Month"

 January 2021

 December 2020

How to make sure that on opening of the report on slicer with "single selection"  

"Last Month" will be already selected  AND when client choose to use "drop down" all values bellow 

 will be listed in order to change selection

--------------

"This Month"

"Last Month"

 January 2021

 December 2020

Thank you

@Alex_G7 , You have create column like

Month Type = Switch( True(),
eomonth([Date],0) = eomonth(Today(),-1),"Last Month" ,
eomonth([Date],0)= eomonth(Today(),0),"This Month" ,
Format([Date],"MMM-YYYY")
)

and select last month, same way you have create for max week of last month and select that.
