Add context_id to transaction_tax & brokers_fee type journal entries

[SefaOray]

Feature Request

It would be great to keep track of transaction_tax & brokers_fee per market order.

Use case

I would like to gain better insights into my production and trading transactions. Transactions tax changes based on unit price and I pay additional brokers fee when I adjust my order, which makes profit calculations very tricky.

Linking transaction_tax & brokers_fee journal entries to market orders would bring more transparency into my expenses and I can calculate more accurate expenses table for a certain trade or production project.
