AI BAS review suggestions for a SMSF

Hi,

I use MYOB for my SMSF to send rent invoices and manage share transactions etc.  AI BAS keeps "reviewing" my entries with a N-T gst code and suggesting they should have GST applied as it sees a dividend payment or a transfer between accounts as sale receipts.  It also assumes a purchase or sale of shares is a personal transaction.  I understand that most MYOB accounts will be for a business, but is there a way to let AI know that the "business" is actually an investment vehicle and the N-T codes I've entered are correct?  It doesn't seem to be learning, even after several rejections and feedback of its not so helpful suggestions.
