SAA-C03 Auto Scaling Doubt

How to create auto scaling group, with instances that start based on schedule?

For example, I would like couple of EC2 instances that start at 8pm in the night and run a batch job. Is it possible to do it with auto scaling group? If so how can I achieve it? I donot see an option in Auto Scaling group to mention schedule based instance launch in Launch Template.
