How to separate short from long term flows/acco in the same TRM transaction

Hi Expert:

My client has lot of TRM transactions as long_term cause their due date is more than 1 year in the future.

Due to legal requirements, regardind the same transaction and their flows, they need to post assets and liabilities that are due before 1 year in different accounts from the long-term ones.

So the question is if there is any way to post short_term flows in different accouts from long_term flows that belongs to the same transaction or there is any transaction or report in trm to do it or shall it be done via Fi module.

best regards

Claudio
