quick explanation.

we have items that are no longer made yet some peopel ask for them, so we'd like to keep the product up yet still have a link stating this could be substituted for for this other product.

On product page we have Red Widgets. The red widgets are no longer made and is priced at 0.00 but a link within the product page shows SUBSTITUTE FOR (link to other proiduct)

yeah i know you can do it manually but was wondering if anyone has this set up on their site where it's done all in the admin end while editing/creating a product page.
