Editing CSS in Enfold

I can see there is a lot of flexibility in being to edit the CSS.

Some changes to colour can be made through Dashboard | Enfold Theme Options | Styling, which is a simple and effective way of making changes. This area also has a ‘Quick CSS’ editing box.

I see that Dashboard | Appearance | Editor shows style.css as a ‘token’ file for WordPress to recognise basic theme data, but is not used by the Enfold theme.

I guess my question is, is there any convenient way of showing/editing the .css files Enfold uses in the Dashboard | Appearance | Editor area, or do the (seven) .css files have to be edited locally in a text editor and uploaded via FTP each time?
