When placing a PDF, default setting for actualization is "keep user-defined visability ...".
Once switched to "keep PDFs visability ...", in the next document it is again on default "keep user-defined visability ..."
I would prefer to have "keep PDFs visability ..." as a stable default for placing.

Example:
1. I added a new Layer to a PDF, but set it invisable by mistake.
2. On actualization, I accepted "new layers visible as in PDF".
3. Later, I remarked my mistake an repaired the PDF.
4. On actualization again, nothing got better ...

I would prefer to know the PDFs as definitly "Masters of visability" ... without having to check objekt-layer-options.

Could you add a preference option, which allows to choose such a manner?
