In Reports only need to show First name, instead of Full name

Can the same separation be done in reports. 

We are looking to show list of those registered for an event via report but we only want to show first names.

No, the native "Full Name" field will display the first and last name, since it is one field.

You can work this out by using two separate "Text" fields, one for the first name, and the other for the last name.
