Customer Journal entry

SOLVED
Hello,
This was raised to me by my accountant.
We have a payment which has been allocated to the wrong customers account in A/R and we would just like to reallocate to the correct one.
We have only found the way throug separately creating a debit journal on the one account and a credit journal on the correct account, but it's not ideal.
here's the query we would like to have an answer for:
