Automatically access git submodules via ssh or https

Question

Question:
Is there a way to automatically checkout git submodules via the same method (ssh or https) as the main repository?

I think I have a more general answer, but it's not quite automatic. There's a configuration setting you can apply in ~/.gitconfig that will replace a particular URL with the one of your choosing.

For Github I have this in my ~/.gitconfig:

[url "ssh://git@github.com/"]
    insteadOf = https://github.com/

Here's a repository with a submodule declared with an HTTPS url that I can clone recursively using HTTPS.

git clone --recursive https://github.com/p2/OAuth2.git

OR

git clone --recursive git@github.com:p2/OAuth2.git

You can read about its use here: https://git-scm.com/docs/git-config#Documentation/git-config.txt-urlltbasegtinsteadOf
