Setting default success codes centrally rather than on each Target Endpoint

[#1]

Is there a way to set the default success codes centrally rather than adding it as properties on target endpoints? Alternatively, is there a way to do it through a policy that we could add to a shared flow? We have hundreds of targets so it's a huge and error prone job to change it this way - and not exactly DRY.

<HTTPTargetConnection>
	<URL>https://...</URL>
	<Properties>
		<Property name="success.codes">2XX,3XX,400,404</Property>
	</Properties>
