Odd number of cards and wrapping them for smaller screens

Hi Balbooa,
I have 6 elements in two rows of 3 elements. Each element will contain an image, text and button. I could make the elements from either Feature cards or just image/text/button in a column.

I have a problem controlling the elements per row, when the screen reduces in size. As there's an odd number of elements, both rows of 3, will wrap to a row of 2 and a single element on the next row. Ideally, the 3x2 elements should wrap to 2x3, then 1x6. Can this be accomplished through the GB interface?

If it's not possible through GB's interface, what would you suggest:
- adding a feature card with 6 items, then adding CSS to limit each card width, to only show 3 per row and hopefully they will dynamically wrap to the screen width?
- adding 6 feature cards each with 1 item in a vertical column, then adding CSS to again limit width and wrapping them?
Or is there another alternative?

Thanks for any advice,
Marcus
