CMS Made Simple Forums

Hello CMS experts out there, I am an SEO LSO expert, but do know little about CMS. Could anyone tell me if there are ready to go CMS packages that have a function which can do automated internal linking.
What I mean is, suppose I upload a new page, the CMS package should look for relevant content in all other pages of the website, and link them automatically to the new page; With relevant anchors (would be nice)
This is the only functionality I am looking for in the CMS package I am looking for. Are there ready to go packages out there, or free to use ones?
Thanks for letting me know.

I am not aware of such package. Hope you'll find find someone to code it. It would be surely interesting feature.
