Additional info on a device

Is it possible to add some additional information on a device?

An integration I am working on creates one or more devices. It sets a relevant name, manufacturer and model. Besides that, there are two more strings that identifies the device, which I would like to appear on the device info card.

An entity can have additional attributes. Aren’t there anything like this on devices?
I have tried to add some additional properties device_info, but they are just ignored.

identifiers is a list of tuples, but I don’t think it is what you are looking for.
I’d like to be able to add some additional information to devices too. Would be really useful.
