title: Partitioning using a substring of the s3 path
body: <p>We have a s3 bucket which has files in the following format:</p>
  <p><code>6ugdasznp56o_2020-09-04T140000_6081c358e0417bdd81284b0cf7a6b321_2853a9.csv.gz</code></p>
  <p>Is it possible to define a <code>storage.location.template</code> as follows:</p>
  <p><code>6ugdasznp56o_${year}-${month}-${date}T${hour}0000_6081c358e0417bdd81284b0cf7a6b321_2853a9.csv.gz</code></p>
  <p>to partition my files in this s3 bucket?</p>
