Resume Enumerate

[Bruce Pourciau]

According to the documentation for the enumitem package, to make the  
counter continue from the previous enumerate rather than reset to 1,  
we just write

\begin{enumerate}[resume]
in the LaTeX file. But in a LyX document, what ERT do I insert and  
where exactly do I insert it? Also, if I generally want my enumerate  
environments to resume counting -- as I do with exams and problem  
sets, for example -- is there a way to make this the default behavior  
by putting a line in the preamble?
