Can we use repetitive ssh-task in bamboo yaml spec?

[아즈냥]

We are trying to move our deployment plans to bamboo yaml spec as it was released in 7.2.4 version. 

We are going to deploy so many instances with ssh task.

These server instances can always be autoscaling.

So we hope  instance list 

We want to automatically get the server list and proceed with the list through ssh task.

How can we use yaml plan !
