Shift Trade back to originator

When a shift trade is canceled between employees AFTER it has been accepted, trading back to the original owner is the only option. This process is fine, but would be nice if the trade back would cancel out the trades within the color legend, reverting this back to the color of its origin.  In most cases, this would be blue.  This would provide more accurate reporting on shift traded hours report and the total hours worked report.  Or adding a trade back category in the legend and reports since the employee is working their base shift.
