SalesIQ filter out users who sign in

SalesIQ filter out users who sign in

I would like to investigate website performance of only those that are not existing clients.

One easy way of doing this would be to be able to filter out any visitor who logs into our website.  We have a specific login page, so I would simply like to filter out anyone who goes to that page (or perhaps the page that follows successful login).

Is there someway to setup that filter?
