Twine: disable link in all passages?

Would it be possible, once a link has been visited, to disable it in all other passages? I could do this with variables, but I was wondering if I could alter the story settings to avoid having to code each instance.

Edit: To clarify, I would still want the text to appear, just not as a link. So, for example, if three separate passages all contained a link from the word tree that led to the same passage, the word tree would then not be highlighted should the player visit one of the others after following the link in one of them.

If not with variables, then I have no idea how that would be done. You could ask on the Twine Forum if you’d like. They know more than I for sure.

Done, and thanks for the suggestion. You’d think after 24 hours I could word the question less clumsily, but apparently not.
