Rename Apple Store receipts based on App name

Hi
I would like to know if there is a way to rename all my app store and itunes subscriptions receipts based on the purchased app or subscription within the document itself?
I have already setup rules for different utility services based on the service providers but seeing as the App store has so many apps i would like to name them based on app purchased.
I usually receive these receipts via email which i then export to pdf and save to a folder which hazel look for but i can't figure out a specific rule to get hazel to look at the purchased content and rename based on that.
I can extract purchased dates add rename that portion but i would also like it to rename the receipt for each app
i.e.. 2017-06-23- Evernote.pdf
2017-06-25 - Airmail.pdf
My thoughts were that i could send the created pdf from email to PDF Expert, which i could then highlight the apps name and have hazel look for the highlighted text and rename but i just can't figure that part out.
If anyone has any suggestions that would be great!!
The apps i have using on my iPhone that could be useful for a workflow are Airmail, Workflow, PDF Expert, Scanbot/ Scanner Pro & Hazel on the Mac side of things
