creating a infurrow spray option when creating a plant activity

WHEN CREATING A PLANTING EVENT WE USE A LOT OF IN FURROW PRODUCTS. I CAN'T SELECT THESE WHEN CREATING THE EVENT.
EXAMPES OF PRODUCTS USED, CIMEGRA, QUADRIS, ORONDIS GOLD. THESE PRODUCTS ARE APPLIED DURING THE POTATO PLANTING EVENT NOT ON A SEPARATE SPRAY EVENT
