How to configure all devices rather than per device at a time?

Hi, I’d like to disable auto syncing feature for all my devices, consider that it will still sync my passwords copied from KeePass even I disabled “include password” option, and currently I can only change settings one per device at a time, and those “default settings” seems to unchangeable now.
To summarize, I am requesting two new features:

  • Ability to configure all devices settings globally, so I won’t need to change those same settings per device.
  • Ability to change the default settings while configuring.
