Crystal XI R2 export to .csv

I have written a Crystal XI R2 SP6 report that looks like this when previewed or printed:

Invoice #       Invoice Amount     Partner 1     Partner 1 %

Invoice #                                     Partner 2     Partner 2 %

Invoice #                                     Partner 3     Partner 3 %

Invoice #                                     Partner 4     Partner 4 %

Invoice #      Invoice Amount      Partner 1     Partner 1 %

Invoice #                                     Partner 2     Partner 2 %

etc, with a maximum of 4 partners per invoice, each on a separate detail line and suppressed if the Partner code is empty using a formula but not actually ticking the Suppress box. The incoming record is the invoice broken into separate G/L accounts, so multiple records per invoice,  and then joined to the customer table, where the partnership information comes from. I reduce this to one record selected per invoice in the same formula with if Invoice = Previous(Invoice).

When I export to a .csv file it looks like this:

Invoice#      Invoice Amount     Partner 1     Partner 1 %     Partner 2     Partner 2 %     Partner 3     Partner 3 %     Partner 4     Partner 4 % (This is all on one line although it may not appear that way here)

How can I have the .csv export look like the printed or previewed report? I do realise that I can export it as an .xls file and then save it as a .csv file using Excel, which works perfectly but is not a long term solution for a daily operation in a business.

Thanks for any help you can offer.
