Commission Rate...

When entering/editing product... under "Price Information" heading we have "Commission Rate" field [there is an empty space under it]... Why don't you change "Commission Rate" field from a number to percentage so we could input 10% or 8% and have the commission calculated automatically based on the "Unit Price"... all you would need to do is add a new field "Commission" below the "Commission Rate"...
