Enable manual transaction splitting for more accurate categorisation

I’d like to suggest adding a feature that allows users to split a single transaction across multiple categories. For example, if I spend £100 at M&S, but £80 was on groceries and £20 on health & beauty, I’d like to be able to assign those amounts to their respective categories.

This would make budgeting and tracking much more accurate — especially for shops where mixed-category spending is common. Many budgeting tools (e.g., YNAB, Monarch) already offer this, and it would be a great enhancement to Snoop’s usability.

I can see this being discussed since 2022 but still not been introduced.
