Formatting Scala code in IntelliJ

I have Scala code like this:

def myMethod(myInt: Int, myFloat: Float, myString: String): Unit = {
//method body
}
I want to format it exactly like this if the line is too long:

def myMethod(
    myInt: Int,
    myFloat: Float,
    myString: String): Unit = {
    //method body
}
So the caveat is that each parameter has to be in it's own line and needs to indented by 4 spaces. I have tried the Settings > Editor > Code Style > Java, under the "Wrapping and Braces" tab, and selected the "Wrap always" option for "Method declaration parameters". But that doesn't indent the code correctly. Anyway to do this?
