Sorry, I'm out.
We'd have the same difficulty speaking to CIC and the cost to us would be significant, just is it is with you. If you want this badly enough, you'd spend the time/money to have your question answered. I know I've spent a lot of money to date to get into a position to apply for EE. If you don't have the money to get an answer to your question then I doubt you'd be able to meet the requirements of EE (WES, IELTS, medical, police check...they all cost money).
I hope you have success in your EE application but I'm afraid I can't help you any further. You need to take responsibility and speak to CIC if you want a definitive answer to your question.
Good luck
