I am using `csquotes` for adding quotations in my thesis and I need to italicize (make cursive) both the in-text quotes (short quotes) and the paragraph quotes (long quotes separated into indented paragraph). 

I have tried the solutions described here: [How to tell csquotes to italicize quotes?](https://tex.stackexchange.com/questions/280619/how-to-tell-csquotes-to-italicize-quotes)

But with the first solution I couldn't figure how to get it to work without switching into French babel (which changes all my headers to French) and it wasn't italicizing the paragraph quotes.

The second solution worked for short quotes, but I didn't know how to adapt it to `\blockquotes` of the format: `\blockquote[citation]{quote}`, as it will italicize the citation instead of the quote.
