Allow better metrics to be applied to the Service Team Productivity tool

[gerrym]

I am struggling with your analytic tool for Service Team productivity. 

We we soon have incoming tickets that may not be solved within the same month as they were created, which means your reporting structure will not capture this piece of data.

It currently only shows create date, count of tickets and if tickets are not closed in the same month - it is not counted. 

Can you please develop this feature as I can see if being quite a versatile reporting tool especially when I have been asked to deliver quick results on the fly.
