Linked list customization using canonical-url


I’m looking for a developer who can help me customize a theme using the canonical-url field so that I can add external curated lists to my website. Ideally, this would be done through code injections so that I can continue to update my theme without additional work.

The effect I’m going for is the one at where some of the posts link back to the original article and others to a featured post within site.

Is there anybody out there that would be willing to do this? Happy to pay for this customization.
