Exchange 2013 - want "send on behalf" to be visible at From field

Hi all,

I did "Set-DistributionGroup -Identity sales -GrantSendOnBehalfTo sales" successfully , Jack belongs to sales group can send message out as sales and recipient will be it come from sales.

But my users want recipient see which sender it come from , mean From field must display "Jack send on behalf Sales" :) .

How can I turn it on ?

Jack
