Add custom dates and other filters to Dashboard

@Chad McGuire (Sparrow Intel) - Combining feature requests for enhancing our dashboard into one for better tracking!

Feature Request #1:
Would like to be able to apply custom filters to the Dashboard to be able to view the KPIs for specific date ranges.

Feature Request #2:
The Dashboard view is great and we really like all it has to offer here; however, we do a lot of weekly reporting, so we would like the date filter here to also be more granular than monthly. The other thing that was noticed that is not here is an Average Star Rating. We see the Volume numbers and Total Reviews, but there is not an Average Star Rating. Also the only Category that we see here is Cleanliness. Is there a place on the Dashboard to find/filter the other Categories?
