I would much prefer to stay saving and reading as a list, it's faster than my previous method of saving individual items as a long comma delimited array (but I'd like it faster still).

Hello Brian,
There may be a (fragile?) way.
Let's suppose you've already written following list
{{"a"}, {"b"}, {"c"}, {"d"}, {"e"}}
to some file F, and that you want to append a sixth element, {"f"}, to that list:
set fRef to open for access F with write permission
write 6 to fRef starting at 5 as data
write {"f"} to fRef starting at (1 + (get eof fRef)) as list
close access fRef
HTH,
Axel
