[RADIATOR] Renaming attributes in Grouped AVP

[Arthur Konovalov]

Hi!

I have a task to store statistics from Diameter accounting messages. 
There are 2 identical Media-Statistics grouped AVP in one message- one 
from Calling-Side and another from Called-Side.

Part of logfile:

I can't store in MySQL table two different attributes with same name.
Is it possible to rename attributes (by script, for example) in grouped 
AVP to excluding names overlapping? For instance by adding prefix or 
suffix to Calling and Called part attribute names.

Please give me any hint, help or workaround.

Regards,
Arthur
