AX 2012 Shared Customer Store code Number Sequence

Is it possible, and if so how, to share a customer store code sequence across companies/legal entities in AX 2012? I have been able to create a number sequence and set it’s scope to “shared” but have been unable to reference this to the customer store code in accounts receivable.I have also gone through the website and tried the steps given in it , but still its not working.
