Ability to Append Info to Caller IDs

Can we have a function in Dial Plans to append to caller IDs instead of modifying, for call tracking purposes. 

This way a call from John Smith to a Dial Plan could be shown as "Custom Text - John Smith" or a call from 1800-800-8888 could be shown as "Custom Text - 1800-800-888".  This would allow users to know whether the call was initiated to just them directly or to which dial plan it is coming through.

Thanks!
