transform the app into a centralized hub for tracking total income

Feature Request: Introduce a persistent income source option in the app, mimicking a bank account setup with, for instance, three different bank accounts and cash in pocket. Once established, these sources should remain constant. When adding income, it should be allocated to predefined categories. Similarly, when logging expenses, there should be an option to select the income category from which the deduction occurs. When adding income, the app should prompt the user to choose the relevant existing category. This functionality would transform the app into a centralized hub for tracking total income and daily expenses effortlessly. Your swift integration of this feature is eagerly anticipated. Thank you!
