Hi @danny620,
You would need a custom module for making this a automatic setup in your administration.
But it could be done manually with some hours of work and a dozen static blocks.
1) Create a static block, name, ex.: OKI 299 put in all models with text + a link.
2) Then add this static block in the description field on the product you wish.
Let me know if this helped you further
