How to filter by camera serial number

Hi forum members,

I have 2 identical bodies except for their serial number. In Lightroom 4/5 I used to be able to filter by camera serial number, which would allow me to filter between the 2 bodies and for example make changes (e.g. timezone/time/date) to pictures from only 1 of those 2 bodies. How can I do this in Lightroom CC (2.2.1)? Thanks.
