Splitting doesn't have to be limited to physical items as well. Service, such as transporting goods, can be split as well.
If you have to drive from coast to cost, especially with large truck, you can transport goods without the fear that there is an overlapping route

The template assumes that this trip is from US West Coast to US East Coast, with approximately I-90 length of the starting state with its approximate cost division for that route, without assuming the toll fee or how dangerous each piece of the toll is

oSplit will ensure only assign reservations if total cost is $1000 (at most $1800, the cost if the entire trip is booked)
However, the organizer should pick either all or none of the participant's reservations - otherwise if the participant wants to transport from Washington to Wisconsin and you only approve Washington to Montana, where would you drop the item?
