You need to figure out when and how to catch her at a good time. If email doesn't work, phone might work better. If not phone, then in person. You might need to print extra copies and catching her at her desk at a certain time of day or day of week when she is more likely to look at them. Some people would want a summary list, other people would want them to roll in separately.
(You don't say how long it would take your supervisor to review each grant request before signing off.)
This! This is totally a question of "managing up." At various points with various supervisors/colleagues, I would email reminders, drop hard copies on their chairs, phone calls, stalk them in person, or send summary emails of "pending" items. You just have to figure out what works for them.
