# Justify left and right inside example environment

I use the "Numbered Examples (multiline)" environment in a LyX document (class : Book (Standard Class)). The text is not fully justified (it is not right justified) in the examples. Is there a way to modify the environment ? I would prefer to not define a new environment and change all my examples into this new environment and I would prefer not to type ERT[\justify] in all the examples.
