Save SSH configuration snippets in 1password

I noticed that 1Password can edit the .config file, and I think it would be nice if I could save SSH connections in 1Password. They could then be automatically added to the .config file.

For example, say I have this connection:
ssh
Host github.com
IdentityFile ~/.ssh/public-key-downloaded-from-1password.pub
IdentitiesOnly yes


I save an Item that links the key to this snippet, and when I set up a new computer, I can allow 1Password to automatically download the .pub key, and add this snippet to the end of the ssh config file.

This would help with security, as I currently only use 2 keys to avoid the six key limit.
