Bundled Sell Rates against Multiple Buy Rate

Hi All,

I have a requirement to map multiple buy rates to bundled sell rate. In other words, 3PL sources multiple BUY RATEs and sell as BUNDLE to their customers.

If any of you encountered this scenario, please throw some light on this?

Example :
1. For a buy shipment having 3 different legs (Carriage, Primary, Delivery leg)
3 Different services providers does provide the service (means we have 3 different buy rate records)
2. 3PL sells the service as Door to Door as ONE rate.

how do we map this requirement?
