Flat view lister layout - how do I alter it?

I have a preferred list layout set up as a style and have made this the default lister. I would like the layout to remain unchanged when I go into Flat View mode, but it doesn't - it changes to a different format. How do I set to not change - or if that's not possible, how do I customise the view?

in Preferences / Folders / Folder Formats, turn off Flat View under Folder Type Formats.

Lovely. Thanks for the rapid response (and great product) Jon.

BTW, I had searched for "flat" in the Preferences search area, but this setting area wasn't one of those displayed.

Cheers.
