title: Can I bulk edit multiple file with VS Code?
body: <p>I have around 50 markdown files with frontmatter. Something like this:</p>
  <pre><code>---
  title: Funny Title
  date: 2020-01-09
  ---
  </code></pre>
  <p>I'd like to edit all of the files such that I have the following:</p>
  <pre><code>---
  title: Conference Volunteering
  dateCreated: 2020-01-09
  dateUpdated: 2020-01-09
  </code></pre>
  <p>That's it. I was able to right a macro in Vim to do this for me, but did not find a way to run this on multiple files. Now I'm thinking there must be a way to do this in VS Code.</p>
  <p>For example, I can search and replace <code>date</code> with <code>dateCreated</code> in all <code>*.md</code> files. That would get me halfway there, I just can't figure out how to also duplicate this line and replace <code>dateCreated</code> with <code>dateUpdated</code></p>
  <p>Any help appreciated. If you need more details/explanations, please let me know.</p>
