How can I attach a persistent EBS volume to an EC2 Linux launch template that is used in an autoscaling group?

To Clarify my Autoscaling group removes all instances and their root EBS volumes during inactive hours, then once inside active hours recreates and installs all necessary base programs. However I have a smaller EBS volume that is persistent and holds code and data I do not want getting wiped out during down times. I am currently manually attaching via the console and mounting every time I am working inside active hours using the commands below.

sudo mkdir userVolume
sudo mount /dev/xvdf userVolume

How can I automatically attach and mount this volume to a folder? This is all for the sake of minimizing cost and uptime to when I can actually be working on it.

Use this code:

#!/bin/bash
      OUTPUT=$(curl http://169.254.169.254/latest/meta-data/instance-id)
      aws ec2 attach-volume --volume-id vol-xxxxxxxxxxxx --device /dev/xvdf --instance-id $OUTPUT --region ap-southeast-1

Set your volume ID and region.
