Is it possible to copy an invite message through the API?

We want to make it really difficult to accidentally overwrite our master survey invite template. To do this, we'd like to create a new invite message for every new survey – that way if you accidentally change that invite, it won't affect invites for other surveys.

Is there a way to do this through the API? I'm looking for something like this, but I want to be able to pass in an existing messageID and have it create a copy.

As a fallback, we could use `Get Library Message` and then pass the message from that to `Create Library Message`. However, this particular message is very HTML-heavy, and I'm having a hard time getting the syntax right for my `Create Library Message` call.
