Okay, fair enough. I will put this on hold then, thanks for the update, @bw-admin!
Could you clarify whether custom item times includes pre-defined (official) item types, or would it be exclusively user-defined templates? The original feature request asked for loading keys into the operating system’s ssh-agent (or providing a custom ssh-agent) directly from within Bitwarden Desktop, similar to how 1Password does it. This would require a standardized way to store ssh keys, which would make user-defined item types as storage for this rather tricky / unintuitive.
