First of all, I do like the ability to make duplicate transactions very much. It speeds up the workflow quite a bit when having to for example manually manage LP token transactions (which still needs to be done A LOT). There is one very annoying (and arbitrary?) limitation to this functionality though - I would REALLY MUCH like to ability to change the transaction type from DEPOSIT to SEND transaction and vice versa. Currently this is not possible, the duplication is only possible as a similar transaction type.
If this limitation would not be there, it would be much easier to make all the manual transactions which still need to be made in many cases where the Koinly app is not automatically interpreting the chain data correctly.
Another new feature that might make your life easier is the Export/Import feature so you can edit the transactions in a CSV, then re-upload it to your wallet to make the changes:
If you do use this, you’ll just have to make sure to swap the ‘To amount’ and ‘To currency’ to the ‘From amount’ and ‘From currency’ and vice versa so Koinly can recognise it correctly.
