More Customized Analytics

It would be great to run most customized Analytics. I like to look the analytics for each month on each of our phone numbers. However, I would like to see more fields to choose from to get more details analytics. I would like to be able to choose "during hours" or "after hours" to know how many of the calls I missed were because of that. Then it would be great to know if 10 of my 100 calls were from the same person who like to call repeatedly while I'm on the other line. In fact, it would be really awesome if I could select that the call was missed because the line was busy or occupied. Thanks!!
