Reply based on NAS-IP-Address

Hello, I have two radius servers (FR v2.2.8) running with postgresql backend. There is modified authorize_reply_query - many SQL joins to get all information required by NAS (for traffic shaping, access groups, ip address, etc.) Everything works fine but... I need to run another NAS (BRAS) from another manufacturer... Another device requires different attributes so i need to rebuild configuration for radius. Is there any possibility to define many authorize_reply_query based on... i don't know, huntgroup maybe? ... or maybe the only solution is to run another instance (with different SQL queries) of freeradius? Thanks for help.
