How can I have an Other Current Asset account appear in the header of a Cash Sale?

As a nonprofit, we frequently receive donations of stock, which are first deposited into a stock account at our bank, then our stock broker mails us a check, less their fees. What we need to record is the following:

Transaction 1:

- Debit to Stock Account (Other Current Asset)

- Credit to Income Account

Transaction 2:

- Debit to Bank Account 

- Credit to Stock Account (Other Current Asset)

- Debit to Stock Commission Fees (Expense Account)

Our issue is that we can't use either the Cash Sale or Invoice forms for Transaction 1 because they only allow Bank Account or Receivable accounts in the header line. Also when we receive the payment and need to record the commission fees, I'm not sure that we could do that using the Customer Payment form.
