Can I Schedule "Updates" To Posts?

I use WordPress to run my review site and I was wondering if it is possible to schedule “updates” to existing posts.

The reason is that I’ll post a review for a product (a) today which will, at the end of the post, reference another similar product (b).

I’ll then write a post for product (b) and schedule it to publish three days later. It, of course, references produced (a) at the end of the post as well.

I would like to have the two references link to each other but I can’t do that at first when I publish the review of product (a) because it would be linking to a post that doesn’t exist.

A good solution would be to create the review for product (a) today and then create the review for product (b) which would be schedule to publish at 1PM three days later, then be able to go back into the post for product (a) and schedule it to update at 1PM the same day product (b) is published with the update being converting the simple text reference to product (b) into a link to the then-active product (b) post.

Is this possible?
