Can i pass more than two column names to split function?

Question

I have split function,in the following way

create function split (@list varchar(max), @delimiter char(1))
returns @shards table (value varchar(8000))
with schemabinding
as
begin
  declare @i int;
  set @i = 0;
  while @i <= len(@list)
  begin
    declare @n int;
    set @n = charindex(@delimiter, @list, @i);
    if 0 = @n
    begin
       set @n = len(@list);
    end
    insert into @shards (value)
      values (substring(@list, @i, @n-@i+1));
    set @i = @n+1;
  end
  return;
end

Using above function we can pass only one column name at a time,
But my requirement is to pass more than one column Names to split function.
is it possible?

Any thoughts Help me
