Thx 😀
Actually I think that the ODBC-import should have an option too, where users could enter the constraintname.
A possible way to do it would be to have a button “edit constraints” close to the FK checkbox (see attached) throwing up the SQL. From here you would be able to change the constraintname and even choose only SOME and not ALL of the FK's to be imported.
I know that support for constraintname must be implemented in SJA-code and the XML-schema too. How complicated that would be I don't know!
