Help with importing from per-directory-history

[TC72]

I've been using per-directory-history and I'd like to bring my history over to Atuin.

I have written some simple python to create a csv which looks like this:

cwd, timestamp, command
/Volumes/Users/tc,1675194859,nvim

What's the simplest way for me to import something like this into the Atuin database?

I've looked around and see #2431 explains after updating history.db you can use atuin history init-store to update records.db.
I could import a csv file into history.db using the TablePlus app on my mac but it wouldn't handle fields like id and session.
(I realise I'd also need to change the timestamp to nanoseconds)

It would be great if Atuin had a simple csv import/export built in. I think it'd make getting started easier. I also think people might be happier giving Atuin a try if they knew there was an easy way to get their history back if they needed to.

nvm, I see this gets very close to a csv export: atuin history list --format "{time},{duration},{command},{directory}"
