Protocol Usage

Protocol Usage

I want to be able to:
 
Display the usage of Spotify on a daily and weekly graph / report.
 
So I have the information port 4070: 78.31.8.0/21, 193.182.8.0/21, but cant see anywhere to either modify port 4070 or create a custom port.
 
Simple chart showing bandwidth usage over a period of time, or anything would be good..
 
 
I would have thought this simple to do but it seems not.
 
running version 7.6 (upgraded to ver 8)
 
using Cisco ASA
