Workflow based on time on page

[Boston]

Looking to create a workflow leveraging the time a known contact spent on the page. For example, if a contact spends 10 minutes on a landing page add the contact to a specific list.

Would be great to be able to create a list of customers who have spent more than 30sec on a specific page like a blog post or something like that to further qualify leads. At the moment you can create a list based on page visit but it would be better if you could say some one who has been on this page for an amount of time.
