Target the people who use Wordpress for marketing, but otherwise have an app. They might pay $5 for this, especially if they are separate business silos. As long as it is super simple to use, this could be a decent non-technical solution to a technical problem.

The challenge is once someone technical is called in, they will realize that this is trivial, so making it possible for non-technicals to easily use (even if just telling them where to paste the code) is essential.

But yes, I have certainly had this annoyance in the past.
