I have a folder "Bills" where I put all invoices and other bills (PDFs or scanned Docs) in a subfolder-system, just like this:
/Bills
/Bills/2011
/Bills/2012
/Bills/2012/12-January
/Bills/2012/12-February
etc.
In Germany some vendors send their invoice-PDFs incl. mutated vowels in the documents name (such as "Ä" or "ü"). In order to turn these mutated vowels into standard letters, I have created an Automator Workflow, which is working very well.
Now I want hazel to apply the workflow on all files & folders inside "Bills". Since the "Bills"-System is quite new and I'm continuously adding new documents in several folders and sub-folders, hazel should apply the rule containing the Automator Workflow on every newly added document or file.
I tried may different rule configurations, but failed:
A. If all [...] conditions for any / all of its sub-files
-> Date last matched is blank
-> Run Automator workflow & (optional) Run rules on folder contents
B. If all [...] conditions for any / all of its sub-files
-> Date added is today
-> Run Automator workflow & (optional) Run rules on folder contents
any many versions with different combinations of the above mentioned rule elements.
I just don't get it

So, any help would be very great, thank you!
Cheers,
Sascha
