Having Firstname, Lastname and Name fields at the same time

Currently, I use both, Firstname and Lastname for registration etc, I am currently setting up a chronoforms form where I would like it to pull both names together in one element.

The easiest way to me would be to have a separate field in Community Builder which automatically at registration fills the field with both firstname and lastname fields.

How would I go about achieving this without changing the default to just a name field? The field itself would almost never change after registration, no need for it to appear on the front end profile and changes would be able to be made from the back end.

Thanks in advance for any help

Firstname and Lastname are already separate in CB within the _comprofiler table. They are not separate within Joomla which stores the full name in the name column. If Chronoforms can pull CB fields into its form then it'd just need to pull the firstname and lastname fields. Aside from that I've no idea what to suggest as we've no Chronoforms integration. If you need just the name as a single value then Chronoforms would need to pull the name column from _users.
