specify your own datatypes based on column-names
e.g. i know that the column 'dateofchange' is always a date-column, and the column 'timeOfChange' is always a time column. And columns like '%prijs' is a currency. It would be nice to set this and when i import an entity, it will be set. Of course you need a check, e.g. mark it when a user-defined type is used.
