Is it possible to import (using odoo csv import) into one journal entry (let's say journal number GJ01) and add all items as child entry, such that it will balance the journal automatically?

Suppose below is my General Journal (GJ) entries csv items.

Number,Period,Journal,Date,Ref,Name,Account,YTD Debit,YTD Credit

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Electronic Clearing Ac," $25,000.00 ",

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Pension Acc.," $25,000.00 ",

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Trade Debtors," $200,000.00 ",

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Prepayment Insurance," $100,000.00 ",

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Prepayment Workers Comp.,," $100,000.00 "

GJ01,May 2015,General Journal,2015-05-01,Opening Balance ,May 2015,Less Prov'n for Doubtful Debts,," $250,000.00 "

I did import using the above csv and it recorded  six records into the object account.move and six records into the account.move.lines. Actually, I wanted one record in account.move and six records in account.move.lines.

Is there any tool or way/s to achieve my goal?

Thanks.
