Automatically download all dependencies when mirroring a package

Question

In my organization we maintain an internal mirrored Anaconda repository containing packages that our users requested. The purpose is to exclude certain packages that may pose a security risk, and all users in our organization connect to this internal Anaconda repository to download and install packages instead of the official Anaconda repo site. We have a script that runs regularly to update the repository using the conda-mirror command:

conda-mirror --config [config.yml file] --num-threads 1 --platform [platform] --temp-directory [directory] --upstream-channel [channel] --target-directory [directory]

The config.yml file is setup like this:

blacklist:
- name: '*'
channel_alias: https://repo.continuum.io/pkgs/
channels:
- https://conda.anaconda.org/conda-forge
- free
- main
- msys2
- r
repo-build:
  dependencies: true
  platforms:
  - noarch
  - win-64
  - linux-64
  root-dir: \\root-drive.net\repo
whitelist:
- name: package1

So the logic of this config file is to blacklist all packages except the ones listed under whitelist. However the problem I'm having is, if a user request package x to be added to the repository and I added package x under the whitelist, it only downloads package x to the repository and not its dependent packages. I've checked the documentation on conda-mirror and the configuration file and can't find anything related to automatically mirroring a package and all its dependencies. Is there a way to do this automatically?
