Project Cost Adjustment Functionality

We have a requirement where at every month end cost will be transferred from a project to multiple projects . Using the seeded functionality , we found we can do 'split and transfer' for a single expenditure item and can only 'transfer' cost from one project to other for multiple expenditure item together. Also, we observed a limitation that for accruals expenditure items adjustments(Transfer or Split & Transfer) are not possible. We are evaluating one workaround of using cost FBDI , to adjust the cost on the projects to mimic cost adjustments (Transfer or split & transfer )functionality .

Could anybody from the community suggest some solution to achieve our requirement?
