Budget - Option to input school fee income by month

Budget - Option to input school fee income by month

Good day,

Some of our fees are billed from February to December. Can the budget be adjusted to accommodate this? Currently, we only have the option to insert the number of learners, the fee, number of months and the system automatically allocates the income from January. This creates inconsistencies between our actual vs budget reports by month. Can we have the option to override the amounts in the months? I have attached an example.
