Allow for editing of header fields of Survey log

It would be very nice if users could edit the header fields in the survey log. Currently, we can not remove any of the fields. Galveston district wants to remove unwanted fields and then add new ones. Perhaps when adding fields make a menu that would allow for a user to do the following
Name field
Type of data (Number, txt, list)

If a list then allows for a table import from a txt list then create a dropdown of the imported list.
