CURRENCY ISSUES IN CASH ACCOUNT

I need to maintain my Naxexa USD portfolio for IBKR reconciliation while having automatic AUD conversion for tax reporting. I am told by AI that the only way to do this is to manually enter each transaction from the USD cash account into the AUD cash account. This would require a manual exchange rate calculation for each manual transaction. Why can you not automate this or place in the manual transaction or modify transaction box a currency conversion tool. You have all the AUD:USD conversion rate per each date anyway. This would make the duplication much easier and would overcome a major problem with Navexa. It would eliminate the manual calculation burden I am facing. I need to to reconcile my IBKR data maually with Navexa as a USD portfolio because Commsec refuse to allow IBKR to provide me with a manual feed despite having the IBKR account number. I need to reconcile manually for performance review then convert my USD cash account from USD to AUD in order to do my tax return. This painful and a major issue for users. Please escalate this conversion urgently to your development team.
