Internal vs External Services

On your next release could you change the icons for web service and internal service check so that we can tell the difference at a glance?  It's very helpful to know where the request is coming from when troubleshooting (especially with load balancers) and this change would denote whether it's coming from my collectors or the ones that you guys own on the web.  I'm thinking just to alter the icon with a picture of a building on the right would say that it's an internal service check.  Thank you for considering this.
