I think that there are two approches to this. Either copy what you have a make a separate forecast application with the budget app as a start. Forecast applications often have other demands compared to budget applications (for example how to handle actuals vs forecast, the level of detail of accounts etc).

The other approach would be to add a forecast dimension to the budget application, but in forecast you often have the need for if formulas that can adjust calculations based on if you have actuals or forecast so you probably will have to alter the budget app anyway in order to get a good forecast model
