Configuring the synchronisation point automatically

hi,
if we want to use survey solution in a big survey, and we installed our proper server and we are faced to install interviewer app in millions of tablets, I now that to use the interviwer app, we enter synchronisation point with credentials interviwer. is there a possibility to configure the synchronisation point (url) automatically (and if possibile without the interviwer can see the url of the server http://adressip:port) in these millions of tablets?
