Planet tile map

Is there a way to control the placement of exes on planet surfaces?  I dislike the fact Earth has 2 exes available in the Siberian tundra while Western Europe, the North American Seaboard and Australia are not covered from the start.  I tried increasing the default tiles settings from 11 to 13 but once again, it's 2 more tiles in the extreme north of America that opens rather than those I want.
