Create a google finance portfolio that correctly reflects my Westfield holdings after restructures

I need help calculating my WESTFIELD GROUP holdings in google finance since the company has gone through many mind bending restructures and now I don't know how to do the accounting for it. Please create a google finance portfolio with the correct buys, sells, etc for the different subsequent company's so I can view my gain or loss for them. I bought 3 parcels (of different amounts) of WESTFIELD GROUP (ASX:WDC) Stapled securities back in 2009. I also had 1 amount of distributions reinvested back to acquire more securities in 2009. Since then the company has had many restructures making the accounting a nightmare. WDC became WDC + WRT which then became SCG + WFD At the end I should only have balances for SCG + WFD in google finance. I've attached the original transaction data.
