I am creating graphs for our network routers. I would like the ability to override or rename the label of the item as shown. 

Very often no one is going to understand "Outbound Traffic on xy0" or "Incoming Bits on gb1", however, if we can rename these in some way it will make for a more meaningful graph. 

I would think this could be an addition to the overrides section or something. 

I hope this is explained properly and I look forward to any discussion on it. Thank you for all work on Zabbix, I am very much in appreciation!
