R12.1.3 -Internet Expenses Change default Employee Liability and Employee Prepayment Account

We are implementing Internet Expenses and we are on 12.1.3. We have enabled option 'Automatically create  Employee as supplier' in Payables Options.

While importing the expense claims, employees are gettting created automatically. However the supplier liability account and supplier prepayment account are coming from financial options.

Our requirement is to have seperate AP Liability ccount and seperate Employee Advances account for Employee suppliers. Is there any way we can achieve this

Thanks
