Hi,
It would be really useful to be able to use a date or date/time field as a Category field within a table when the table type is set to 'Grouped values'. This would mean a table of unique survey dates etc could easily be created with summary statistics e.g. number of records collected on each day etc being able to be created and linked to other map elements.
Currently the work around to this seems to be to create a string field containing dates, but this isn't ideal as the dates then appear in numeric order in the list when sorted rather than date order.
