title: How to name a list of a group_split in dplyr when grouped by more than one column
body: <p>I am using group_split in dplyr and I am struggling to name the list after I have split by more than one column.</p>
  
  <p>I know how to do this when we group by one column <a href="https://stackoverflow.com/questions/57107721/how-to-name-the-list-of-the-group-split-output-in-dplyr">here</a> but I am not sure how to do this when splitting by two columns</p>
  
  <p>I can't share the data but if using the iris dataset, it would be similar to this (in my case both columns are factors)</p>
  
  <pre><code>iris %&gt;%
  group_split(Species, Petal.Width)
  </code></pre>
