We can use MAXROW() like:
MAXROW(Customers, SignupDate, [State] = WA) — returns the most recently created customer from WA state.
But it seems that we cannot use CONTAINS() inside of the MAXROW() like:
MAXROW(Customers, SignupDate, CONTAINS([State] , WA))

By the way: The Help page for CONTAINS() is not available.
