Yes, but you would have to have a database where the larger task has the items you need for to complete it.
For instance
Code:
tblTasks
TaskID TaskDescription
1 Wrapping Presents
2 Washing Clothes
tblEquipment
EquipID EquipmentDescription
1 Laundry Detergent
2 Dryer Sheet
3 Tape
4 Box
5 Scissors
6 Wrapping Paper
tblTaskEquip
TEID TaskID EquipID Qty
1 1 3 1
2 1 4 4
3 1 5 1
4 1 6 2
5 2 1 1
6 2 2 2
So that whenever you added a task to your list you could add up all the different items you needed and the quantities of those items.
