I know this was only released 3 days ago, so please see this as a request from an enthusiastic user....
2.3.6.142 introduced the preference on all devices to define an attribute to use for a device status on the devices and rooms pages.
I thought I would apply this in bulk across different device types using Preference Manager, but noticed this is not currently available. Which is fine, it is a very new feature and this is purely a request for convenience. I see @ritchierich got in before me in suggesting that it would be nice to see this setting in Preference Manager, I just wanted to do a more formal request.
