Resource name in activity details & search function

Summary

Looking for a field, which would include bucket's or technician's name to provide quick information where activity is

Hello, 

I'm looking for a field, that would include the name of the resource (bucket or technician) which has the activity in. We are using the new Core App. In old legacy manage, the resource was shown in parentheses, for example "Activity Details (John The Technician)" when we opened the activity. (See attached image for example).

I would like to get that information to activity details page so when dispatcher's open activities, they could easily see who has it. Also I'd like to add this field to the search function, so we wouldn't even have to open the activity to see who has that activity in their bucket. I tried "resource.pname" but it's only for the users name who is logged in, and not the resources name which has the activity in. Also, not all these fields are available in the activity configuration because it only includes activity type properties and not resource type properties.
