Clang-format customization options


I’m trying to customize .clang-format to format project code. One thing I wasn’t able to customize was function arguments being combined into a single line - even if the line is within the established column limit, I would like to be able to split the argument line into multiple lines if I so desire. After browsing documentation I wasn’t able to find such option. Did I miss it or is it currently impossible to format code in such a way using clang-format? If so is this a customization you consider adding, or is it not a desired option (inherently difficult to implement or just undesired)?

Best regards,
Michał Szostek.
