NSF/Return check with intercompany One Cash to multiple AR/GL

Our current NSF process is to Unpost the deposit, Credit a DR item and apply the deposit to the new DR item - this works well when the AR, CASH & GL BU are the same; but not when different.

In the creation of pending items(DR Item) accounting entries - the GLunit are fixed and cannot be change thus we cannot fully reverse to CASH without a manual reclass

Are we missing a step in our setup?
