I have a To-Do action that allows the user to enter several fields, one of them is a URL for a document. As I can't have a lookup (we do not have Nintex Forms) I have created a page which will display the documents for the user and allow them to Copy the URL.  I would like to at least put this link near the field for the Document URL. I have tried to use several fields but they expect the user to create the hyperlink and I just want to display one.

There are 3 fields then the Document URL Field then a Comment field. I'd like the hyperlink to appear between the Document URL Field and the comment field. Any ideas how I might be able to pull this off? (basically I want to be able to put static text on the form as part of the content type.
