I've gone around the circle with quite a few HubSpot support folks who suggested that I add this as an idea here.
The problem I'm trying to solve is how to exclude site traffic from my colleagues. The traditional answer is that you can use IP filtering, but that only works with a company in an office space, which is not true of my company that was going mostly remote (and is definitely not the case right now in the middle of the COVID-19 crisis for most companies). My understanding is that the ISP that employees have at home is almost certainly going to assign a dynamic IP address, so you need to be able to continuously update your IP filtering, which is not possible at the moment.
One hacky way this might work is have all employees fill out a form on the website so they get a cookiee, create a List of them, and then exclude that List from reporting. It's the last step that's not currently possible.
