Template Repeater - Best Fit - Ordering Direction

Is there a way to change the direction of ordering of items in a template repeater with a best fit layout? I would like the items to be ordered in columns first instead of rows.

Desired:

1 4 7
2 5 8
3 6 9

Actual:

1 2 3
4 5 6
7 8 9

The repeater must function for a wide variety of display sizes, so changing the order of items in the template parameters dataset is not a viable option.

No, unfortunately not. Unlike flow layout, BestFit decides on row-based ordering and doesn’t have any ability to override.
