title: Recommendation for more than one last viewed item
body: <p>Currently I have a Recommendation block (Recommendation logic- items with similar attribute) at home page. Here the entire block get tuned and limit the suggestions only to the last viewed item. I wanted to increase the recommendation (incoming feeds) for atleast last 2 or 3 viewed items.<br>
  **For example-**Currently If user visits items Z > Y > X  then the recommendation blocks gets filled with items which has similar attribute only to item "X" (leaving last to last viewed).   I would like to explore the possibility of recommendation block having track of items Z, Y and X.</p>
