While I think what you need is a database instead of the collection of
csv files the way to alter namedtuples is to create a new one:
from collections import namedtuple
Row = namedtuple("Row", "foo bar baz")
row = Row(1, 2, 3)
row._r

I have a lot of NamedTuples in my codebase, and I now add new ones never. They
were a good option prior to Python 3.7 but dataclasses are much easier to work
with and are almost a drop-in substitute.
A combination of a default dictionary and a dataclass might meet your needs:
