Customer on-account item reclass -> PeopleSoft AR module

We want to reclass customer payments that are applied to on-account (not to items). Is there a process within PeopleSoft 9.2 (PUM41) that can allow that functionality.

This is needed because items are coding to one department (e.g. dept id 100) and on-account payments from customer are coded to another department (e.g. dept 200) , so during maintenance worksheet while adjusting on-account payment with customer items, departments are not netted to zero.

Thank you!
