hey folks, I have a question about tuple lists: is it possible to use tuple lists for batch inserts when one of the values in each tuple needs to be cast to a custom type? So, as a minimal example, after supplying this tuple list:

[["some_word"]]

[[CAST("some_word" as my_custom_type)]]

or do I just have to iterate over single insert queries to do this?
