Accurate cost calculation

The timeframes/costs have been designed the average cost per hour calculation doesn't take into consideration the number of working hours in the configuration settings, it uses the 8 hours regardless of this setting.

As 8 hours is not applicable to our business, we have different working hours in configuration setting. We have to recalculate cost manually when we use cost data from Promapp.

It would be great if the cost calculation formula take consideration the number of working hours in the configuration settings.
