Unit Metered - Unit Meter Reading

In the Unit Meter Reading dialog, under Unit Metered, would it be possible to change it to have fields as below:

  • Black & White Meter

  • Colour Meter

  • Total Meter

  • Cost per Copy (B&W)

  • Cost per Copy (Colour)

with the Total Meter automatically calculated from the first two fields.

This would enable my business (Photocopier Sales & Service) to actually use this function as at the moment it’s very limited & therefore useless to us.
