When it comes to finding your previous Lists from yesterday, you can find this in the following section of RiTA:
Here you'll be able to change the assignee (if you have admin access) to view their currently in Progress lists (today's ones) or Completed lists.
Here you'll be able to find your Lists from yesterday, as well as any other Lists you've completed in the past. Here you'll be able to adjust the 'Date Completed' to your desired dates (by default 1 week).
Clicking on the relevant tile of your choosing will allow you to open up that past completed List, seeing all the relevant contacts that were in the List at the time of it's creation.
