Initial Load for Customers/Vendors to CRM

Hello all!

I'm going to do Initial Load Customers/Vendors from SAP ECC to SAP CRM.

My question:

1) if customer has number 1111 and vendor has number 1111 - I want to create 1 bp with different roles.

2) if customer has number 2222 and vendor has number 3333- I want to create 2 bp with relationships.

Is it possible in standard?

Thanks
