How to save indent to PDF?

Creating an indent with the Confluence Rich Text editor results in the following code (Confluence Source Editor):
<p style="margin-left: 30.0px;">Indented text</p>

How can I recognize the indent intention in the "Content Formatting" (CSS) section of the Scroll PDF Exporter?

According to https://k15t.jira.com/browse/EXP-397 there is still no resolution for this Confluence standard formatting issue, right?

A tedious workaround is to insert manually or per macro a class attribute and to address this in the "Content Formatting" section:
<p class="Indent1" style="margin-left: 30.0px;">Indented text</p>

I would be glad if someone has a better solution!
