Hyperlinks in the Invoicing Specs

A client is requesting a change on their Invoices that they email to their customers, using the Invoices module.

I need to include a hyperlink in the footer of a spec that in effect, reads: “Click here to view our Privacy Policy”, and is followed by the hyperlink, such as https:/www.blahblahblah.pdf.

I am able to do this when I use a Label-type field, and I enter the actual hyperlink site as a separate entry.
However, if I rename the hyperlink to: Privacy Policy and this is what is displayed on the Invoice, the hyperlink is not functional.

Is there any way that this can be accomplished?

Not that I know of.

The link to the privacy policy should be in the email body rather than the invoice footer.

Doug - I had not thought of this. This is a nice alternative to having the link in the document itself.
Thank you for the suggestion.
