In my reports i select a data  filter Talk number: and i select the zendesk number.

I also make sure to show (display) the choosen filter attribute on the report. 

So the manager who sees the report will see also which filter has been selected (the phone number will be visible under data filter)

Now instead of displaying that Zendesk number, which is a number the managers don't know by  heart; i would have preferred if i can make an 'alias' for this number ; let's say i 'll name the number Brand C phone number.

So in the report instead of the Talk number visible , it would nicely show : Brand C phone number.

And this for all the other numbers we have from Zendesk. 

Could this be implemented?
