Can Multiperiod journals in AP be deleted for future periods?

Hi

Once Mutliperiod accounting journals have been created for a prepayment covering future periods, is there functionality to delete some of those journals or is there an altern? Thanks.

Example being if 6 months into a 12 month contract say for maintenance, the contract is ended but the underlying journals for the remaining periods have already been created but not yet posted in the GL. Can that be handled in AP without voiding original invoice or booking manual journals in each future period to reverse the entries?
