Mutiple distributions for single invoice line throgh AP invoice import

Hi

Can we create mutiple distributions for one invoice line through payables open interface program. I want this for custom source and distribution amounts are not constant to use distribution set and these are also not tax lines.

I have checked from invoice entry screen where i can able to enter data as per my requirement but i want same functionality through import program.

Please advise what is format i need to take care in AP interface tables

Thanks
