R12 Grants Accounting - how to enter Project related expense reports

On 11i we enter project related expenses in Grants Accounting using the pre-approved batches form with a class of Expense Report.  It appears that this option is not avaliable in R12.

We do not use iExpenses here and expenses are entered centrally from expense forms.  So I am looking for suggestions on getting expenses on to projects  in R12.    We can't use Invoice Workbench as not all employees will be suppliers.

This is what the upgrade document says:

You can create project-related expense reports in Oracle Internet Expenses or Oracle Payables. However, you can no longer create them as Pre-Approved Batches in Oracle Grants Accounting, and they are no longer interfaced to Oracle Payables.
