I have a requirement to allow editors to insert a "More" link inside an accordion (to encourage users to open the accordion), but my problem is the client's branding/css requires the "More" to be inside a <span>, which should itself be inside the last <p> tag (or whatever tag is the last block in the text).
So I'd like the editor to be able to insert their own <span> tag just as they can insert an <a> tag or similar, i.e. highlight the text and hit a button. From there I can add a custom style they can apply to the <span> tag to accomplish the "More" requirement.
I've also considered adding the "More" in code, but it's a difficult task trying to figure out which is the last paragraph or element in the XhtmlString.
