Append a string to the end of all rich text links I'm trying to append a string to the end of all rich text links. Is there an already existing plugin for this?
I found a way to use the RetconHTML plugin for what I wanted. I just utilized the Attr filter and it worked the way I wanted. I had to also remove the way Retcon would add spaces to appended strings.

{{ block.paragraph | retconAttr('a', { href : '?some_text' ~ entry.title|kebab }, false) }}


By including false, it adds to the already existing href, rather than overwriting it.
