Output "Same as source" for multiple output tasks

[torakiki]

This would make sense for

• single input multiple output: the output files are saved in the same directory as the input document
• multiple input multiple output: as described below by the feature request.

From the PDFsam forum:
Hi there,
What would make a good program even better is the ability to save the output pdf back into the same folder as the source pdf even when you have added pdfs from several different folders to the job list.
For example: if I wish to rotate several pdfs from different folders I would just put a "." in the "destination folder" pathname and it would overwrite or save a renamed copy of the output file in the same folder for each individual file.
Regards,
Darren
