Possible to concatenate related model attributes?

[polycode-nz]

My User model has first_name, last_name.

Is it possible to concatenate the two attributes in the log?

This works:
logOnly(['Creator.first_name'])

Obviously only logs the first name.

I have a public accessor getFullName
logOnly(['Creator.getFullName'])

errors with: App\Models\User::getFullName must return a relationship instance.

Went around it by using tapActivity()
