On the customer reports, Detailed Order History (aka~ My Order History) report page, please add a column with the customer name and a way to filter by it, just like the My Orders page does.

The purpose is our clients would like to see, filter and download this report based on a particular employee to see what they purchased, how much they spent and how often they are making purchases. This is important for clients using budgets -- especially shared budgets -- or allowances.

I've included a mock-up for clarity.
