dependent flexfield on the purchase order of an account in the PO Charge Account

Summary:

I would like a flexfield that gives me the option of yes or no depending on the account used in the PO Charge Account.

This flexfield in the best case scenario would be automatically populated if the specific account is in the combination. If it doesn't work automatically, the value list should only include the option relating to the account.

If the account is not being used, the return must be "N".

Is it possible to create a dependent flexfield in this sense?
