LibreOffice Draw; Open PDF - Lacking default styles

Hello, I’m running LO v4.3.3.2, Build ID: 430m0(Build:2) on Debian Jessie (64bit) with the libreoffice-pdfimport package v4.3.3-2+deb8u3.

I finally figured out how to create a new Style and save it in a template, then make that template the default for new Draw documents. However, I need those templates when I open/import a PDF. Currently, when I open the PDF, my newly created styles go away.

Ideas? Thanks!
