Different weights for types of feedback

Hi,

This is more of a feature request than an issue.
Would it be possible to add weights to feedback?

Usage:
Our webshop has 2 possible feedbacks at the moment: "add to cart" and "placed order".
I would like to add "view product" as a feedback but this would skew the current feedback in favour of "view product" while this is less important than "placed order".

Thanks
Maarten
