Problem description: 

Steps to reproduce:
1. I create a new document, spreadsheet, etc.
2. I save it in the native format (odt, ods, etc.)
3. I export it to PDF.

Current behavior:
The default directory in which pdf export is directed is the last directory where I exported my last pdf file. 


Expected behavior:
There should be a button on the Export dialog with the following label: "Saving Directory". This button should navigate in the file structure from the lasd pdf exporting directory to the directory in which the document (odt, ods, etc.) resides. 

Explanation:
I have to send some different letters to many different places. I write and save them in odt format in different directories (according to their destination) and want to export their pdf version in the same directory where the odt file is. Now it is a painful method to navigate to the proper directory before exporting and to take care of not overwriting a previous pdf file.

Thanks.
