Worksheet - ability to add columns to represent different years

We have initiatives that span multiple multiple years.  We use worksheets to calculate the budget for the initiative.  Budgets are aligned by fiscal year.   

The current problem is Aha does not allow us to add additional budget years as a column.  I have to create a whole separate worksheet to represent each additional year.  

Goal would be to add additional columns to one worksheet to represent each years.  We would need to be able reference this table and associated column in Aha reports.
