Dear Philip,
I don't think that is possible in the workspace handy for all the months. But if you want, you can edit every month once like the below.
Right-click on compare the time period and set the custom date range: I have set it to compare 1-4 April with 1-5 March. This will be valid until the end of the month. Next month, you should edit the same to re-configure.
Thank You, Arun
