I need to link in the registration of each new host through the mandatory information of a numeric or text field, with a length of 11 characters, which I will call CPF.
However, if the new host has been indicated by another host (already registered) I would like to include other optional information in the numeric or text field, with a length of 11 characters, which I will call CPF_LINK.
How can I include and customize these new fields in the hosts register?
Note on screens 01 and 02, how the CPF and CPF_LINK fields will be included.

screen 01
After confirmation of registration by email, the host informs EMAIL, PASSWORD and CPF -
SCREEN 02
The value of the CPF field is transported to screen 02, and there is a new CPF_LINK field to be filled in.
