Deploying nodes using EM changesets/templates

So I am trying to learn the EM. I want to deploy 50 nodes to a LTM. So I created a template like so

 

 

@define @node_ip

 

@define @node_name

 

F5[Local Traffic / Node]

 

F5[$target_partition$]

 

node @node_ip {

 

session disable

 

screen @node_name

 

}

 

 

The template seems to be fine, so then i go to tasks>stage a changeset

 

 

I select my template, then the LTM.

 

 

So this is cool, it allows me to enter the value's for that one node. Is there anyway to expand on this, and make it so i can deploy a bunch?
