Hello,
There is only one option right now, configure one device as you need and download the configuration backup. It will save every single detail of configuration and can be uploaded to another same type of router. If you want to transfer only certain parts of the config, you will need to download the troubleshoot file. Once you have it you can open it and see every single config and upload it to another router via WinSCP or any other SCP file transfer program to another router.
Regards.
