Reformat string to match specified line length

Hi,

We decided to set the line length of our IDE (IntelliJ) to 200. 

However, when trying to automatically reformat the code, it is not reformating strings that "broke" into a new line to match the new line length. 

For example, I want this:

assert retrieve.data["accounts"][0]["balance"] == 0, "could not find the right balance" \
                                                     f"expected - 0, retrieved - {retrieve.data['accounts'][0]['balance']}"

To turn to this (after reformat):

assert retrieve.data["accounts"][0]["balance"] == 0, f"could not find the right balance expected - 0, retrieved - {retrieve.data['accounts'][0]['balance']}"

Thanks
