Tagging Items in Sub-Sub Folders

Hi there!
I just came across this software and really like it as far as I can tell yet. But I didn't manage to achieve what I downloaded it for. I have many Folders that constantly change and I need to tag whats inside of them. An example:
A folder called "Companies", with many company subfolders which each have a folder called "Invoices", like that:
I Companies
I-- Company A
I----- Invoices
I------- invoicexy.pdf
I-- Company B
I----- Invoices
I------- invoiceABC.pdf
I want every file inside of one of these "Invoices" sub-subfolders of Companies have an "Invoice"- Tag. But I don't want to create a new rule for every Company folder since there are hundreds and its just getting more.
I tried out a lot and also tried to find a solution in this board. Found a lot of interesting possibilities, but nothing that really solved my problem. Does anyone have an Idea?
