This is a great idea, and, as you know, you can find this information by using custom time ranges, but it sounds like what you want is a single report that compares this type of data through time.
I have automated some of this by using the REST API to inject "application deployment" events - a custom event that contains teh application build number. Depending on how automated you are, this can be done by having your application build tool send the REST request into AppDynamics with the correct information on which build of which application was just deployed.
Once those events are in the controller, you can find them (again, with the REST API), extract their timestamps, and use the timestamps to retrieve (again, using the REST API) key preformance indicators for the appropriate time window. For example, you could retrieve response time for key business transactions and CPU utilization, etc. for a certain time period just after each successive release and compare this to each other - I chose to take the result of the REST calls in XML and use XSLT to create an HTML report, but other options are possible.
Anyway, just some ideas about how you might leverage the REST API to do some of this in an automated way.
If automation is not required, the "Compare Releases" feature can be used to gain some of these insights, although it only compares two time periods.
Hope this is useful.
