Can I get the nextline in an excel sheet for same request?

If I have 2 rows of data in my datasource (excel doc), each representing a customer, and in my soap objects I can send more than one in the same request;

Can I use line 1 for the first customer object in the SOAP obj, and then use line2 for the next object, all within the same request.This is how I'd like to be able to fill an interation of objects in the SOAP envelope.

Thanks!

EDIT: spelling and clarity
