Manage Transaction Page : Salesperson to be split as First Name and Last Name and shown in different fields

Content

Hi,

On Manage Transactions ,Salesperson name is appearing as full name ,that is first name plus last name.
Requirement is to see First name and Last name in separate fields on Manage Transactions.

Using Page Composer I can add Text Field but do we have string functions which we can use in Expression Builder to split Fist name & Last name.

Regards

Udit
