How to import stock transactions?

When I try to convert stock transactions, all the fields are set up as banking transactions.

The converter needs to be able to import these fields:

DATE,TRANSACTION ID,DESCRIPTION,QUANTITY,SYMBOL,PRICE,COMMISSION,AMOUNT,NET CASH BALANCE,REG FEE,SHORT-TERM RDM FEE,FUND REDEMPTION FEE, DEFERRED SALES CHARGE
