Why yes, there is: openstack stack resource mark unhealthy

That command will change the resource status in Heat to CHECK_FAILED. That will cause the resource to be replaced on the next stack update, unless the autoscaling group is scaled down in which case it will be among the first to be removed.

This command was not able to find the instance name when used as the resource name. Is there a way to mark an instance (particular VM) as unhealthy so that when we update it rebuilds all the VMs that are marked as unhealthy.

You can use the UUID of the server to identify the resource beginning in Ocata. Prior to that it had to be the name of the server resource in Heat. Server names are too ambiguous. There's no way to force a rebuild instead of replacement.
