We have a new scenario where we want to be able to charge a customer $0.50/weight over 20kgs. They only want to charge for the weight over 20kgs so if it was 25kgs it would be 5 x $0.50 = $2.5
Currently the only way to do this would be with a sliding scale with a per in range charge, however you can't start a sliding scale at 20, nor can you enter a $0.00 value for the first range.
If we can remove the validation to prevent a $0.00 value, then we can configure this with an allow Zero charge and use the existing per in range functionality. If it is preferred to tie the ability to enter a 0 value into a sliding scale is dependent on turning on this Allow Zero Charge flag then that would be ok.
