title: Any way to have key/value pairs as template variables on grafana?
body: <p>i am building a couple dashboards using grafana and i found the templating feature to be very useful, however i am monitoring some ec2 instances and getting some metrics from cloudwatch's ec2 namespace, however those use the instanceid as parameter, since the instanceid is not really human readable, which brings me to my question:</p>
  
  <p>Is there any way to have key/value pairs as templating variables for a dashboard? that way people would see the hostname, select it, and the right instanceid would be fed to the panels,</p>
  
  <p>Thanks in advance</p>
