title: INDEX-MATCH All values, and concatenate/textjoin all matching values into one cell
body: <p>I have the following data:</p>
  
  <p><a href="https://i.stack.imgur.com/ElYXZ.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ElYXZ.jpg" alt=""></a></p>
  
  <p>Columns A thru D have the data set.
  In the bottom half of the image, each "Code" and "Title" are listed only once, and the "Phase" column displays all the "Points" under the respective "Code" value. The Index-match for Phase and Code value only return the first matching Code value; I would like to insert a formula to automatically concatenate all the matching values and list them as shown in the image. Please help!</p>
