Option to include Income (sub)categories in the Budget

Hi,

as the title suggests I think this would be a very useful addition. I use budgets for all sorts of things but sometimes have to calculate myself to compensate for the income in a very specific subcategory e.g.
I’ll have a budget of 100€ for lending people money and I get this money back I want the budget to show that.
or more common: I receive money for a specific subcategory every week and also have expenses. I need the budget to keep track of how much I can spend but for that the budget needs the new income amount (!)

Thanks for considering and for the great work :)
