How do I draw down CPF OA and SA account for my retirement?

Currently, there are 2 options for you to do this.

1. Create a scenario, edit the CPF OA or SA and then do a yearly withdrawal. This method is linear and it will stop once there is no more money in the account.
2. Create a scenario, withdraw all the CPF and create an investment recommendation and use the drawdown feature to drawdown by period or by amount. This method will have more flexibility in the drawdown but it will not reflect the growth of the CPF account accurately.
