Customising elements that are created from the toolbar

Hello,

Please could you tell me if what I am trying to achieve is possible
with plone/kupu..

basically, I would like to customise, for example, the lists so that
when a list is created it is created with class info such as <ul><li
class='content'></ul> etc.

Obviously, i cannot just override the style for <li> in a skin since i
need the editor to add the class info (this is picked up later on in a
live site exported from Plone)

Any info would be appreciated. I guess the question is how I customise
elements that are created from the toolbar...

Many thanks,
Nic.
