iSupplier Responsiblity to update supplier record

Hi,

We wanted to know if anyone tried using iSupplier module to update supplier record for supplier type of employees. We process employee expense reports from Payables module where every employee record is converted to a supplier before expense could be reimbursed. We are thinking to provide iSupplier responsibility to employees so that they can update their banking info, however, not sure if this would be possible and what complications this could have. I will truly appreciate your past experience if you have used or know about the use of this functionality.

thanks
