Export encrypted key

If I need to export my private key for use with something that doesn't support 1Password's agent (e.g., anything on iOS), I'd like to be able to export it encrypted, but this currently is not supported. For instance, if I want to SSH via Readdle's https://readdle.com/documents, I need to export the key and store it in a path within the app's local storage. I would greatly prefer to have it encrypted.

OS Version: macOS 12.3 (21E230)
