Voucher Excel to CI - multiple voucher line upload

Hi,
I am new to PeopleSoft Finance - Accounts Payable Module. we are using voucher excel to CI load and sometimes there are invoices with multiple distribution lines and if we enter them in the current template it creates duplicate invoice issue. how do we enter the invoices with multiple line using voucher excel to Ci? thank you in advance for your help.
