When using the Funraise Data Source, there is only one date option in the selection screen (shown below).
Currently, the Funraise API only supports specifying changes or additions made in the last number of hours. We translate that into a date from date but there is no way for us to add a date to to the API filter.
When you select a date in the selection screen, that will pull the changes/additions that have happened in Funraise since that date/time.
