Universal AudienceStream attribute which identifies Desktop / Mobile Phone or Tablet

[kirill_petrov74]

Hello,

I'm curious if there is any universal AudienceStream attribute which identifies Desktop / Mobile Phone or Tablet? Something like a Device Type? 

I see it can be done through the User Agent attribute but it should include a lot of rules so I'm wondering if there is any elegant and quick solution to it. 

Many thanks!
