Overwritten nodes in configurations

[JimCircadian]

Due to the Batch defaults that are set via namedtuple in config.py, run specific values are overwritten when specified as default in the root vars of configurations. We should identify when these are being replaced in the batch context by None and ensure they aren't overwritten, as a placeholder for some clearer work in the future.
