open/close shortcodes or other method?

I’d love to see this plugin adapt open/close shortcodes or some other method than just targeting a specific div or class. I wanted to target an entire section of each of my blog posts for the Print Me button, so I used a div class. But, using that div class, I was unable to use headings or other similar formatting within that div class without breaking the div class that I wanted to print.

Example from my post follows. I’d love to know how you’d suggest printing a large section of each post (i.e. podcast notes) that would contain its own formatting. Thank you!

This should not be printed.
<div class="fieldnotes">Field Notes
This is how it works.
<h4>But adding this Heading 4 breaks the div class.</h4>
[print-me]
See here.

<ul>
<li>point one</li>
<li>point two</li>
<li>point three</li>
</ul>
Thank you so much. Please print.
</div>
Nor should this.
