You can't do it with visibility. In V7 when you haven't set a project information parameter it won't show anything. So we use this technique to achieve what you want.
I don't know how to make the images inline, hopefully this will make sense:
Open your Titleblock and add a label. Create a new text shared parameter (here called NFC).See attached image. Format the text label as required.
Now open your project(template) and add the new Titleblock.
Go to settings->project parameters and add the shared parameter to project information categories. See attached image.
Now when you go to project Information you will see the label and you can edit the text. Or leaving the label empty will not show any text across all sheets that use this titleblock.
