EEX 9.1 - Expense Role Exceptions Question

When setting up Location Limits, Expense Roles and Expense Role Exceptions, we have run across a problem, and I have a question related to how the functionality should work.  In configuring the Expense Role Exceptions, the admin has to specify the Expense Type, Country, Role Rate, etc.  The question is about the Country.  Is that Country related to the Employee's default country, or to the country specified on the Expense Location?

Here is an example...  We have an employee based in the USA.  We have two Expense Locations: one in the USA, and one in GBR.  We have two Expense Roles, JUN (Junior) and SEN (Senior).  A JUN employee has a Location Amount for Lodging for the USA location of USD 100, and a Location Amount for Lodging for the GBR location of GBP 50.
