Consider a transaction
```
2025/04/09 * Invoice
My:Bank
Expenses:Accessories €100.00
Expenses:Business:Tax €20.00
```
If I define
```
= /Expenses:?/ & %/\\bTVA20\\b/
My:Bank -0.2
Expenses:Business:Tax 0.2
```
The above transaction can be written as:
```
2025/04/09 * Invoice ; TVA20:
My:Bank
Expenses:Accessories €100.00
```
But I don't want to hard-code `My:Bank ` in the automated transaction (what if in another transaction I want to use `My:Other:Bank` instead). It would be nice if in the automated transaction I could access the account that balances the transaction and subtract from it an additional 20%. Can this be done?
Thanks
