Hi Shanvi Rishi! You can use Little Math's Override function to set all quantity slides to show icons in a grid pattern.
You'll find the "Icon Placement" setting under "Display & Sound" > "Icon" in the Override Settings window. Make sure you apply your changes in both the "Numbers" and "Expressions" tabs of the Override Settings window.
Please refer to this articles for instructions on how to use Override:
