Hello, Rob,
One way would be to configure one router with those basic settings, then make a backup, load it on another router and then make other changes that you do manually. For the backup to work, routers have to be on the same firmware version.
The other way would be to access your router's directories with programs like WinSCP and copy files from /etc/config/
If you want to have settings preloaded to your routers or for them to save even after a factory reset, you would have to contact your sales representative.
