Dear Friend ,
I didn't get reply yet. I think its not possible.
I have a idea but I dont know how can I make
if possible any user dont write mail adress and system automaticly add default mail adress in background . Is there anybody help me for sample code ?
default mail adress is firstname.lastname@example.org .
And any customer dont write mail adress system automaticly include email@example.com and after next order system make automaticly counting and add firstname.lastname@example.org . and other email@example.com .
