Time Range "Save as"

When doing analysis for a specific time period in the Dashboard/Select time Range, it would be nice to be able to “save as” user time range on top of the “Pin” feature. This way we can come back later without having to rebuilt the time selection. Also, it would be useful to be able to switch between two (or more) time ranges to make faster comparison analysis. This can be accomplish by creating a user preset selection box, for example adding 3 checkbox on the top of the Select Time range.
