Waiting to act until multiple files match the right criteria

Hello All,
I had a question about combining pdfs and I wasn't able to find an answer when I searched, most likely because I don't know how to word my question effectively
My family and I run a small, eco-friendly pest control business. I am just beginning to help in the office and I am trying to automate as much as possible. Here is a common scenario that repeats every day for me.
Scenario:
Phase 1
On Sunday night I log into my company's website and download 3 separate appointment lists. 1 appointment list for each technician.
Hazel currently watches the downloads folder and looks into all pdfs to find these appointment lists. Based on the information it finds, it then renames the file according to the appropriate work date and tech name and moves them to a folder called "Unprocessed".
The end result is a have a folder that looks like this:
2017-04-01 -- ANTHONY -- Appointment List.pdf
2017-04-01 -- SALVADOR -- Appointment List.pdf
2017-04-01 -- MASATO -- Appointment List.pdf
Phase 2
On Monday after the work day ends, I download 6 more pdf reports which show what work was actually done and technician notes to the office based on that day's work
I have a hazel rule for each of these as well, they all get renamed as YYYY-MM-DD -- (Tech Name) -- (Report Type). So as Monday comes to an end the unprocessed folder looks like this:
2017-04-01 -- ANTHONY -- Appointment List.pdf
2017-04-01 -- ANTHONY -- Completed Appointments.pdf
2017-04-01 -- ANTHONY -- Notes to Office.pdf
2017-04-01 -- MASATO -- Appointment List.pdf
2017-04-01 -- MASATO -- Completed Appointments.pdf
2017-04-01 -- MASATO -- Notes to Office.pdf
2017-04-01 -- SALVADOR -- Appointment List.pdf
2017-04-01 -- SALVADOR -- Completed Appointments.pdf
2017-04-01 -- SALVADOR -- Notes to Office.pdf
--- So here is where I get lost ---
I would like a hazel to watch the "Unprocessed" folder and look for files with the same Date AND Technician Name, then trigger my Automator workflow (which I already made) to combine those files so I have a folder that looks like this
2017-04-01 -- ANTHONY -- Workday Reports.pdf
2017-04-01 -- MASATO -- Workday Reports.pdf
2017-04-01 -- SALVADOR -- Workday Reports.pdf
I have no idea how to go about doing this?
Any help would be much appreciated
