I would call each admin office personally if you have the time. If not, drop an email.
Calling is beneficial and you might even get an interview from it!
Bottom line: don't request changes to be made by AADSAS: it takes too long and the new changes might generate more errors. Besides, since you are in the first batch of apps., schools are going to review your AADSAS application and make some form of decision on you before AADSAS even sends out any changes you request.
I'm sure we'll all hear from most schools in 2-4 weeks, whereas AADSAS might not even update schools with your changes in that time frame.
