2-color vector fill

Hi, in the old CorelDraw versions it was very easy to create my own 2-color vector fills using the blue grid (under "create" button) but none of such exists in X7 or does it? Im really struggling to find it or easily create my own. Im frustrated after few hours of trying just to create dotted fill where I could change the 2 basic colors (background - fill). Any help will be appreciated!
Thank you
Jiri
