Add "Last X Days" options to report

My Power BI report feeds off of one table which has, among other fields: 
TimeStamp
Reading

I use a line chart to plot Reading values over time -- so TimeStamp is on the x axis. 

Since there's a lot of history, users are requesting some shortcut options:

(_) Last 7 days
(_) Last 30 days
(_) Last 90 days
(_) All time

Ideally these option would show up in a single-select slicer. When selected, the data set and visual would filter down to the date range selected. 

I was able to easily implement one such option by adding this measure to my table: 

Last7Days =
VAR _max = MAX(Table1[TimeStamp])
RETURN IF((Table1[TimeStamp] > _max - 7) && Table1[TimeStamp] <= _max, "Last 7 Days")

I can put that in a slicer by itself and when the user clicks the checkbox, the visual filters to show just the last 7 days. 

How can I implement more such options and make them mutually exclusive?

@bvy  You can create a parameter table that has two columns:

* the text labels (ie "Last 7 days")

* the days to filter (ie Today -7) 

 

Then follow a similar method to this: https://excelwithallison.blogspot.com/2021/08/categorical-date-slicer-in-power-bi.html
