Ability to Configure Interface within Templates

Hey.
Is it possible to give the ability within the template to set the Host Interface to use for each item instead of having this within the host items itself??
Within that fix would it be possible to allow the same template to be added to the same host more then once??

My situation is that i have multiple Java process on 1 system and id like to monitor them with JMX, and within that i dont want to have to clone the template and make minor key changes to be able to apply multiple JMX checks.. perhaps have the validation setup for interfaceid or perhaps even the template name rather then specific to the key..
