How to run seperate databases?

[Delphi]

Hi there just bought PT3 blind.
Installed it with postgres.
My first action was to create different db's for the sites I'm playing (Everest, Party, Full Tilt).
Now I wanted to import my Full Tilt hand in the FT-database etc.

How do I select which database which hands are suppose to go into?
I don't seem to be able to select different DB's for different sites on the import preferences tab.
When I select everest and want to define the preference that everest hand should go in the everest db, this preference is also used for the other sites (or so it seems). In PT2 I was asked which of ny active open dbs should be used.

I sometimes play different sites at the same time and need to be able to direct hands in the correct site-db.
BTW where do I find the DB's?

This is not possible yet, but will be added.
The databases are not stored in single files - postgres manages lots of files for each DB.
