R20110 - Creating Exp Mgmt Documents using MultiCompany Single Supplier

Hello All,

We have to find a way to create expense management documents without creating cross company transactions.  Today if an employee charges expenses to a business unit outside of his home company, a cross company transaction is created.  We are trying to find a way were the multicompany single supplier program can be invoked during the "create voucher process" of R20110.  My developer looked at R20110 but could not really see where this may be possible. 

Any suggestions would be greatly appreciated. 

Best regards,
