Add savings to budget categories

It would be great to have the option to include savings in the budget feature.

For example, if my monthly income is $100, I’d like to allocate $20 to my Emergency Fund, $10 to Investments, and $70 to spending categories such as Groceries. At the moment, the budget feature only allows me to allocate money to expense categories, while transfers to savings accounts or Smart Goals are excluded.

It would be really useful if savings accounts and Smart Goals could be included in the budgeting process, allowing users to allocate 100% of their income across both spending and savings. This would support a true zero-based budgeting approach.
