multiple SQL instances on a single server

HI guys

i got a new project opened in which we have to configure huge number of SQL policies on NBU master server. 90% servers have multiple instances on each win 2008 servers.

as of now what I do is i create 2 policies 1 full , 1 incremental for each SQL instance on a server. now i hav got servers in my environment which hav 8 SQL instances on a single server. i ended up creating 16 different policies for a single server.

Is there a way or method to backup diffferent\multiple SQL instances of a server in a single netbackup policy ??
