Action to 'Save As' to child folders

Hi everyone,

I work for a publishing company that creates ads for multiple publications and part of my job is to design an ad in Illustrator, and save it as a PDF in it's lowest quality for proofing and another PDF in it's highest quality for press. This is a bit tedious so I've set up an action to automatically save the Illustrator as two PDF files and in two different folder locations but I discovered I need to create this action each month and for each publication because the 'Save As' function saves the PDF to a certain folder location path.

The file system is always the same each month for each publication:

• Publication name
  • Year
    • Month

• Ads
  • Proofing
    • (Low res PDF files)
  • PDF
    • (High res PDF files)
  • (Illustrator files)
• Editorial
• Layout

Currently the save as function has a path like '/User/Publication/Year/Month/Ads/Proofing' so when I move onto the next month and use the same Action it overwrites the previous months files. Is there a way to set up a 'Save As' function that saves the PDF files in the correct child folders automatically so I don't have to keep creating new Action's every month for each publication?

I hope that all makes sense. It's a bit of a tricky one to explain.

Thanks in advance. Matt
