detect http or https and apply target="_blank"

I am trying to build out a hyperlink and want to add target="_blank" only if the link contains http or https in the url? Is there a macro for that?

Example: {% if (BannerImageLink "starts with http or https") {"target=\"_blank\""} %}

transformation if

You can do something like this:

<a href="{%BannerImageLink%}"{%if (BannerImageLink.StartsWith("http")) { " target='_blank'"}%}>Link text</a>

Here's a really good article on using the Macro Console.
