Easy transfer of budget.

Let’s say I have 1000 dólares to spend. I would like to budget this 1000 dollars into different categories so I don’t overspend (that’s the envelope method for personal finance). But wouldn’t it be amazing if we could easily “transfer” amounts from one budget to another? So if I accidentally overspent in clothing, for instance, I could exactly determine in which categories I would need to spend less in order to cover that extra spending.
