enumeration depth

[Staffan Ringbom]

Hi,
The default enumeration style in lyx is
[(1)], [(a)],, [(i)] "number, letter, i" something like this

1.
   a
        i
    b
         i
         ii
2.

Would like to skip the first level and get directly to the second enumeration depth as 
default.

Is there any quick fix (in the LaTeX preamble)??

(The nasty way to do it is to export the file as Latex and force the
enumeration with \begin{enumerate} [(a)])
It would be more productive to do it directly from LyX. Any suggestions?

Staffan.
