VI Import - Split a data row into multiple detail lines?

Hi,

We want to import a sheet from a client that sends us a csv of monthly invoice info.   Some lines on the csv need to be split into 2 and occasionally 3 lines, based on the data.

I can parse the line fine, but is there a way to have multiple detail lines created for the singe data line in this case?

The answer may be "no" but thought I would ask.

Thank you.
