Lead First Name/Last Name

Lead First Name/Last Name

Hi, I'm testing zohocrm and even though I have first and last name fields in a lead record:
1. When I specify last name, firstname as two separate fields in a view, it shows the full name and alphabetizes by the first name.
2. The report tool only shows "Lead Name" as a column option, instead of the separate firstname and lastname.
I need to display and report based on last name. Any suggestions?
