which functoid to use ?

I have a flat file schema where a row comprises of a Department number and 5 phone numbers.

I want  to map it to a flat file schema where you can get the department number and telephone number combination in five separate records for the five different telephone numbers of the department.

What functoid should i use for this purpose ? Directly linking the 5 telephone number tags in the Source schema to the telephone number tag in the Destination schema did not work. 

(The Department number and the five telephone numbers are identified by relative positions.)
