Hexagon Grid snap to vertices

I creating a game where i want to draw hexagon tiles, which works perfect with the hexagon grid.
However, i also want to draw tiles on the vertices of the Hexagon Grid.

I have a work-around with creating a new rectangular grid, but this lets me snap to other points then just the vertices of the Hexagons.

I'm wondering if there is a feature or option i can use to snap to the vertices of the Hexagons.
