Custom email HTML layouts

Hello

There are 3 email designs: plain, light and dark.
Is it possible to add our own HTML layouts, or replace one of these?

Thanks

In v4, are the ‘light’ and ‘dark’ HTML layouts real files that we can replace? Or is it somewhere hard coded?

The files are here:

Ahh great, thank you hillel.
