Tell us about your request

Once we have for each we can generate resources in easy way, then usually we want to have them in monitoring dashboard.
But dashboard body is a far away from being friendly. We need to declare the same view N times..

But also we have toJsonString and join

So I want point the need to have dashboard body like (pseudo code)

body:
    Fn::Join:
	  - Fn:ToJsonString:
	        - Dashboard Title
		- Some non repeatable views
	  - For:each:Alarms:
		- AlarmName
		- - Ref! alarm1 
		  - Ref! alarm2
		- View for ${AlarmName}   

There is also alternative - to dynamic dashboard body item resource.

Are you currently working around this issue?

Currenlty I have ugly yaml that describe dashboard transformed with Fn:ToJsonString...

What is the expected behavior with this new feature

The expected behavior is to have possibility of the Cloudwatch dashboard body generation through for each.
