AUTOMATICALLY merge based on the body text

Does the tool contains the capability to AUTOMATICALLY merge PDFs into one file based on the text in the PDF?

E.g. I have report for each Customer.

Each Report:
*it is only one page
*unified format
*Report name is the Customer name
*Report format is PDF

Customer may belongs to different country.
Country name is text in the report.

I want to compile all Customer reports for each country in alphabet order.

Output:
One Report contain:
· Country X
o Customer A
o Customer B
o Customer C

· Country XX
o Customer A
o Customer B
o Customer C

· Country XXX
o Customer A
o Customer B
o Customer C

etc.
