How can I implement in the standart xml einvoice more G/L accounts?

I receive from a third party ocr software all my supplier invoice informations, but I do not now how to feed the interface to ifs.

For example:

I have one supplier invoice, but the positions has to pay with two different kind of G/L accounts.

Which XMl tag should I add on?

Thank you.

Cheers
