The multiplier functionality doesn't currently allow splitting.
However, here's a couple of things that might help.
- Swipe - Try swiping an item button towards the order. Swiping adds the base item to the order quickly, plus any default required mods. This is far quicker than using the multiplier.
- Two finger tap - For more complex items with mods added. After the item is added to the order, tap the order item with 2 fingers. This will clone the item.
