I have a partial solution.
Target the class by putting this at the top of the Custom Notification
<style>.FS-H1 {display: none;}</style>
It leaves a large space between the bottom of the body and the inserted report. I played around with other styles but couldn't find a way to clear the margins, padding, or style the alignment. The %recdata% with a form works but it's not 100%. I may try to do some negative styling or a float and update.
Leaving this here for future searchers with HTML and CSS experience. Below is the notification with things removed.
<style>
table.t1 {border-collapse: collapse;}
th.t1 {border: 1px solid black; padding: 3px; text-align: left; text: bold;}
td.t1 {border: 1px solid black; padding: 3px;}
.FS-H1 {display: none;}
</style>
<p>Hi, <br>
<br>
<p>lorum ipsum dipsum lumpsum</P>
<table class="t1">
<tr>
<th class="t1">Company Name</th>
</tr>
<tr>
<td class="t1">[Company Name]</td>
</tr>
<tr>
<td colspan="4">
%recdata%
</td>
</tr>
</table>
</p>
