Analytics report - number of content downloads?

Dear support team, 

I am trying to build a monthly report under Marketo - Analytics to get the total number of downloaded assets into our website. 

Today, the numbers I have from this report are:

- the total views

- conversions 

- new names 

But none of them refer to the exact number of downloads.

Is there a way to get an extra column in the report that will give us the answer or do you have an other suggestion to make?

Fyi, our web users need to fill out a form to get an email with the download link (the links included in our emails are .pdf documents taken from the design studio directly). 

Many thanks in advance for your help.

Kind regards,

Ljubica
