Related Products or Upsell/Suggested Products

Is there any way to get a related products box or a upsell / suggested item box on the product page?

Example,

1. customer navs to page selling “Salt Shaker”

2. page shows “Related Products”, “Pepper Shaker”

3. page shows “Suggested Product”, “Organic Sea Salt”. This may require admin to go to “Salt Shaker” and manually link the “suggested products”

Thanks
