The new spatial connector in 10.2 is amazing. However, when analyzing spatial data in a time series, some additional functionality would be nice. Specifically, I'm finding that analyzing historical spatial data often requires the merging of multiple shapefiles (say one for each year) into a single file. It would be fantastic if Tableau could UNION together multiple shapefiles. Keep in mind that this would require some ability to mark each file's data with an identifier so the original source is clear.
