To add an option to deduct amount
It would be great if an option to deduct money can be added.
For instance, suppose i have paid 1000 for the bill, but due to some voucher the bill amount was reduced by 15%. In this case i did the splitting of each item to the respective pupils according to the money specified in the bill. But in the end of i want to deduct 150 from each persons share it's not possible.
Deducting 15% from each item seems tedious.
It would be great if this could be added....
