Filter if a data point (lat/long) is outside of a travel area

[JayDeckerMBA]

Hi everyone! First time posting here so please be kind. 

I'm currently using the travel area feature to calculate the drive time for our service folks and to plot customers within a 2 hour radius. It works well but I'm wondering if there is a simple way to filter on customers that are outside of that service radius rather than manually clicking on everyone outside the shaded area? 

Thanks for any help!

Just an update, I tried to go the Within route thinking I just needed the opposite of it but I'm running into some roadblocks
