Changing Position in EPII

Dear Ms. Gravitas,
I would like to get your advice for changing position in my EPII.
Currently I am working as Customer Service Manager and it's going to complete for one year.
Now, I have received the renewal notice from MyExpat (Immigration).
Before renewal my permit, can I change my position to Export Manager ?
The reason why I would like to change is;
My company always ask me to communicate with overseas customer for export arrangement until documentation. Export processing became under me.

Before our company submit my renewal, could you please guide me what are the thing we need to prepare for changing position ?

Thank you very much for your advice always !!

It will not be a renewal that is required but a full approval process for the new job. A competitive selection will also be expected
