Forcing a PGP key onto keyrings

Does anyone know a way to make sure that a specific key be automatically added to every keyring in an organization?

I have an ADK, but using the DLP-PGP endpoint agent integration, I can only add an alternate PGP group admin to the PGP ACL if the key already exists on the endpoint's keyring. It could be any key, but in my case, this would be a PGP group key.

I would just like to make sure that every keyring in the org contains a key or keys specified by the PGP admin.
