Trigger sidekick restart on main service restart

Hi,

We have a scenario where we have a service, A, with a number of sidekicks, lets call them a, b, c, and d.

When service A restarts, for whatever reason (like, the application died/exited), we need the sidekicks a through d to also restart.

Is there any way to set this up in rancher, or would that be a feature request?
