Printing to PDF in Step 7

As part of a submittal process, I must print my project in PDF form. It seems that I must open each block separately, select Print, then direct the output to my PDF writer.
Is there a way to do this with one command or at least shorten the process? I have about 300 blocks spread over seven processors. I have Step 7, Ver 5.3 w/ SP3.

I just tried it with FreePDF, and it worked fine. From the Simatic Manager, I selected all of the blocks, right-clicked, and chose "Print". It created a PDF file of all of the blocks.

All of my code is in STL, so I don't know what the output format defaults to, but I would think it would use whatever the block properties are set to.
