Cross-reference link that does *not* replace my text

I'd like to add a cross-reference link to my selected text, but every option I try in the Cross-Reference Formats dialog *replaces* the text I highlight. I want my text *style* to change, not the text itself.

Example: in this sentence, "All features from the basic module can also be used within any advanced module.", I want to link 'basic module' to a relevant section in the document. I do *not* want to insert the page number or section title; I just want the link added to the existing "basic module" text.

Does anyone know what I'm missing? Thanks in advance.

(If you're wondering why I don't want to add page numbers or section titles, there are 2 reasons: because I have 100s of cross-references and the document becomes unreadable with all that inserted info; because it'll just be a digitally-viewed PDF that no one will ever print or care about page numbers.)
