Splitting during interest posting

Hi gurus,

Is it possible to split and group the posting of an interest document to different lines according a customer criteria?

Example, interest run over a document with the following lines:

Main 0100, sub 0020, division 11

Main 0100, sub 0020, division 11

Standard behavior: interest document posted with one line.

Required behaviour: interest document posted with two lines, one with the amount calculated over Main 0100, sub 0020, division 11, and one with the amount calculates over Main 0100, sub 0020, division 11.

Thanks,

M.
