~~Would it be possible to have a command which will build a given config and then trigger a submission automatically once the build completes? This would be especially useful in a CI system where we cannot wait for the build to complete.~~
--- As mentioned below, this is possible with the --auto-submit flag, I've just tried and it's working nicely for both platforms. To that point, I'm updating this post to be a request to add this feature to the documentation. It is currently not listed in the docs for either eas build or submit (or anywhere else that I can find, besides the --help in the CLI).
