On any given day I might be accessing different aws systems with

I'm looking for a way to basically templatize (new word?) the hosts
file.
It's called dynamic inventory
Example:
this_track=track4
this_subnet=239
[group1]
ax.$this_track$.ecm ansible_host=10.$this_subnet$.1.5
ansible_ssh_private_key_file=/home/me/.ssh/me_rsa
ca.$this_track$.ecm ansible_host=10.$this_subnet$.1.6
ansible_ssh_private_key_file=/home/me/.ssh/me_rsa
[group2]
if.$this_track$.ecm ansible_host=10.$this_subnet$.1.7
ansible_ssh_private_key_file=/home/me/.ssh/me_rsa
ui.$this_track$.ecm ansible_host=10.$this_subnet$.1.8
ansible_ssh_private_key_file=/home/me/.ssh/me_rsa
Ideally I would set the this_track variable at the top of the playbook
file, but I'd be OK with something like this.
With a custom script you can do all this and more.
