Feature Request: Multi-Categorization of Transactions

[SunFlowerOwl]

Describe the feature

I propose adding the ability to assign multiple categories to a single transaction within the application. This feature would allow users to associate a single financial transaction with several categories, reflecting its multifaceted nature. For instance, a single expense could be categorized as "Office Supplies" and "Marketing" simultaneously. Additionally, users should be able to enter a specific amount for each category to reflect how the total transaction is distributed across categories.

Why is this feature important?

Better Financial Insights: Transactions often span multiple purposes, and restricting them to a single category can lead to incomplete or misleading financial reports. Multi-categorization provides a more accurate breakdown of financial activities. You could do that by splitting transactions but its less user-friendly.

Enhanced Reporting: Users can generate more detailed and precise reports that better reflect their spending patterns and income streams.

Improved User Experience: This functionality aligns with real-world accounting practices and would make the application more versatile and appealing to a broader user base.

Additional context, screenshots, and relevant links

I would suggest something like that to allow the user to use this feature:

@SunFlowerOwl appreciate the idea here, but we will generally be sticking with 1 category per transaction. To achieve your use case, we'll eventually be implementing nested categories - #1211

To get even more granular, you can apply both a category and multiple tags to a transaction.
