How to distiguish between Heading hiarchy? #4207

I use PP-DocLayout-L for PDF analysis.

Detected labels:

• image
• text
• text
• text
• text
• text
• text
• text
• text
• text
• text
• doc_title
• paragraph_title // H1
• text
• paragraph_title // This should be H2
• text
• figure_title
• paragraph_title
• text
• text
• text

As you can see, there is no distinction between H1, H2, and H3. Is it possible to make this more specific? I need a heading hierarchy.
