I did try using a raw HTML string ... "<a href="blah">blah</a>", but to no success (I cannot recall the error currently, but SS threw a runtime error in this case.

I’ve done this by adding the field as free form text and using an html string, then setting the display type as Inline.

<a class="dottedlink" href="' + url + 'id=' + id + '" target="_blank">' + text + '</a>
