How to change ERT alignment in LyX to "left" instead of "block"?

[John Kirollos]

Hello There,

I'm trying to customize the ERT inset layout a little; LyX displays text 
in ERT layouts *block aligned*. From the customization documentation, I 
found no "align" parameter for the inset layouts (only for styles, 
taking values such as Left, Block...).

Is there a way to configure it left-aligned? I find this to be more 
convenient & readable.

Thanks in advance,
John
