docs: Call sumSeries after inserting wildcards at the given position(s).
  
      Example::
  
          &target=sumSeriesWithWildcards(host.cpu-[0-7].cpu-{user,system}.value,
                                         1)
  
      This would be the equivalent of::
  
          &target=sumSeries(host.*.cpu-user.value)&target=sumSeries(
              host.*.cpu-system.value)
