The import dialog does not use presets, but it does remember previous settings.
Click the "import" button.
At the top of the dialog, click the "copy" option.
In the options on the right, click the checkbox "make a second copy to", "choose", navigate to your external drive.
In the "destination", navigate to your internal drive location.
After you finish this import session, the next time you do an import, these settings should be remembered.
