Reporting on PDF Downloads

[Anonymous]

I set up a trigger to reward leads w/ a score of X number of points if they download a PDF. Smart list: 

Clicks link on web page - link name contains .pdf
Clicks link in ANY email - link name contains .pdf

If I want to see the number of leads that have downloaded a PDF in the past 6 months, how would I go about doing this? I thought I could create a smart list and add "Downloads Any PDF" as a filter, but that is not listed as a filter. Is there a way to make this a new filter?

Use

Visted Web Page CONTAINS ".pdf" OR Clicked Linked on Web Page CONTAINS ".pdf"

You can also use Filled Out Form if that's how we permitted the download...or even Program Status = X if we know that always happens for a dl.
