AP Payment request from Expenses Module created for Legal Entity of Employee, how can we change LE?

Summary:

AP Payment request from Expenses Module is created for Legal Entity of Employee,

How can we change LE or on the Payment request, or for the existing Employee?

This employee was working in HQ Office, where his user was defined in the system to HQ Legal Entity, after, the same employee was transfered to work in another Branch, releted to another Branch Legal Entity and he reported his Expenses from the Branch.

In AP module Payment request was created from Expenses Report in Branch BU but for HQ Office legal Entity - which is wrong, and now the Branch can not pay to Employee his Expenses.
