How to change default Exchange Databases/ Text Connection Settings/ Field separator

Hi,

I often create form letters and have to connect to different databases in Writer.
I use the Edit/ Exchange Database/ Browse to pick a db, and then there is the Text Connection Settings dialog prefilled with Field separator ‘,’ and Character set ‘System’. And I always have to change these two into ‘;’ and ‘UTF-8’.
Is there a way to overwrite the defaults for these fields?
