Manage external apps or URLs for incoming calls - add option for "external calls only"

We use the option to provide pop up information (website) about the customer for our customer care team and it is really usefull. The issue is the URL is opened for every incoming call, including internal ones.
Is it possible to add the option so the internal calls can be excluded (I mean the external app or the URL is not activated for internal calls but still work for external calls)?o

Would be nice to have the option available for RC Phone and RC Web/App so the option is there for whatever the app user use.
