Is any way possible to get events counts for which stream's value is < 5

Question

Hi,

Below stream Insight query works perfectly fine while stream's values is greater than 5 and it's giving Count.

 var w = from m in sourceStream.Where(p => p.Value >= 5)
                    group m by new { m.A1, m.A2 } into x
                    from tw in x.TumblingWindow(TimeSpan.FromMinutes(5))
                    select tw.Count();

Now when all of the stream's values are less than 5 for a tumbling window of 5 minutes, the count won't gave any result.

I know the reason that streamInsight is designed like that, but is there any way to extend so that it will give Count = 0
