Splitting bills across categories

[cheetahbyte]

for each transaction, there should be the option to split the price across multiple categories

Example

A bill from the supermarket may contain items belonging hygiene and food and not just goods from one category.

Possibly there needs to be a change that decouples the balance in an transaction from the transaction itself. A table "payments" might be needed, that consists of balance, category and the tid (id of transaction). An transaction can contain multiple payments or just one.
