Feature Request: Using the 'Text Change' being able to search and replace html

It would be great to be able to search and replace html (not just text).

The replace text feature is ok, but sometimes we might have to replace wording and include a link or make content bold which this doesn't work as the html code gets messed up.

Also if needing to replace a sentence that already has html in it, it won't work. eg:

To join, simply click on the <strong>Sign Up</strong> button and then complete the registration details.

Can't change that sentence as it contains the 'strong' tag. If enter the above including the html tag, get major warnings (see screen shot attached).
