Format Traversable using the configured column width?

[asarkar]

Given some Traversable like the following:

val xs: Array[Char | Option[Char]] = (
  'n', 'k', 'u', 'c', 'm', 'p', None,
  'a', 'h', None, None, None, 's',
  None, None, 'g', None, 'q', None, 'e'
)

scalafmt puts each element on a new line.

val xs: Array[Char | Option[Char]] = (
  'n',
  'k,
  ...
)

which makes it really long.

1. Is there a configuration to format the array using the configured column width? Each line may not end exactly matching the others, as shown above, but a best effort will be good enough.
2. If not, is it possible to retain the user formatting? Currently, I'm forced to enclose the code with format: off and format: on.
