Suppress bullets for certain levels

[Warren Young]

I'm aware that you can suppress all bullets when printing, but I  
would like to suppress them only for levels 1 and 2 of the outline.   
These are my major header levels, so they are bolded.  That and the  
fact that there are relatively few headers is enough to set them off  
for my purposes.  If I turn off all bullets, the items underneath  
these sections appear to flow together, so the bullets are helpful  
for them.

If there is no way to do this right now, consider it a feature request.
