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 http://blog.ignify.com/tag/sequence-in-microsoft-dynamics-ax-2012/ and tried the steps given in it , but still its not working.
