Select Many in Analytics

It would be great to be able to select multiple stores when running analytics - i.e. in the dropdown for choosing a store, you can currently only choose one store at a time or "All Stores". 

Would also love the ability to add metadata at the store level configurations such that we could tag different attributes of a store, such as its Division number (so we can filter reports by Division), and even let us add our own dynamic attributes (such as "Field Specialist"), such that we could run reports for stores that are covered by each specialist. 

the onboard analytics are pretty good for basic stuff, but having to go store by store or having to do all stores is a bit limiting.
