Hi @User! I have defined similar conf inheritance patterns in the past by modifying the

register_config_loader

hook under

src/<package_name>/hooks.py

. __**Example**__

from pathlib import Path
class ProjectHooks:
    """Project hooks."""

    @hook_impl
    def register_config_loader(self, conf_paths: Iterable[str]) -> ConfigLoader:
        # Force local as ultimate overriding params, regardless of env chosen.
        conf_paths.append((Path(CONF_ROOT) / "local"))
        return TemplatedConfigLoader(conf_paths, globals_pattern="*globals.yml")

In this case, the inheritance will be

base

->

<custom_env>

->

local

. You can append other envs to

conf_paths

to customize this behavior.
