Vertical Grid - Records per row.

In PHPRunner 10.7, records per row in the vertical grid maxed out at 10. In PHPRunner 10.8, records per row in the vertical grid is now up to 15.

Is there anyway in PHPRunner 10.7, I can increase the records per row to 15? Is it just a CSS change or does anyone know which output file would control this amount.

I have already purchased 10.8 just don't want to upgrade this application yet to 10.8.

Thanks in advance for any direction.
