Variables in a widget

Hi there, just came across your fantastic WP plugin, I wanted to ask if it would be possible to use on Widgets.

i.e. I have a Widget I re-use across the website, with
a) A call now button,
b) A form for people to request a call back

Would it be possible to pass a variable to the GA Event, so I could tell where this was used ?
If I just add a class all the goals would look the same, I want to know which page it was called on.

thanks
