Can we enter an Expense Location Amount for Hotel that includes Room and TAX?

Our customer manually enters Per Diem for Hotels using the Expense Location Amount tables. A designated user enters a new Expense Location and Expense Location Amount as needed. See enclosed document with a sample page shot of some of these Expense Location Amount entered. For example, Location WAOLM has an Active Average Amount of     $ 99.00, with Active high Amount $ 0.00 and Active Low Amount $0.00, Benchmark Average Amount $113.00, Benchmark High and Low Amount of $ 0.00.

When a user enters the Expense Type HOTELWA, the system only allows $99.00, which is the room rate without tax. They try to manually add an Active High Amount and Active Low Amount values that will include Room + Tax, tested but the system still will only allow them to enter a max $99.00 rate for this row.
