Hi,

is there a way to change indentation for quotes and quotations in the preamble 
of a document? I'd need left indentation 0.7cm, right indentation 0cm.

All I found was changes inside the document, such as:

\par
\begingroup
\leftskip=2cm % ggf. verstellen
\noindent Langer Text
\par
\endgroup

Not a very encouraging option when you need to change about 1,000 quotations.

Thanks for your advice.
