Group concat up to a maximum number of rows in SQLite

I want to group concat several rows, but only up to maximum number of x rows. Here is the code without the maximum

create table if not exists csvs (
  id integer,
  csv text
);

insert into csvs (id, csv)
values
  (1, 'one'),
  (1, 'two'),
  (2, 'three'),
  (2, 'four'),
  (2, 'five'),
  (2, 'six');

select id, group_concat(csv)
from csvs
group by id;

This yields: id | group_concat(csv) ---|--- 1|one,two 2|three,four,five,six What I want to achieve is this (so a maximum of 3 entries per row): id | group_concat(csv) ---|--- 1|one,two 2|three,four,five 2|six Is this possible?
