Mapping of Text type to Aurelius

I have defined a very large datamodel for a  with over 150 tables and used the stringtype Text as that is recommanded by PostgreSQL as the default datatype for strings.
I have now created the export for Aurelius and found out that this datatype is mapped default to TBlob, instead of (what seems logical) <Nullable>string.
I know I can change the fields from TBlob to <Nullable>string, but that is a very cumbersome procedure for so much tables. Is there a way to speed this up, or to change the default that the Aurelius export uses for the Text format?

Unfortunately there is no configuration yet for a generic converter between data type and Aurelius type. You can only change the types specifically per property, as you mentioned.
