dynamic matrix for store opening date

Hello everyone, I ask you why I can not solve a problem of visualization

I have to create a table filtered by date on store sales, the result must be like this:

my problem is that I can not make sure that depending on the opening date of the store the matrix divides the stores into two subtotals, the first containing the stores that were open in 2017 and the second those that were opened after the first date of analysis.
statically I can recreate it but not if I use date selectors for analysis, for example in the same dashboard perform the analysis February 2018 and January 2018.
the table should change depending on whether the year before was open or not
