"hide empty description" for composite states with only outputPin

Question

Hi! It is possible to hide white space for composite states if they not contain inner states, except outputPin, inputPin, etc.? For example:

@startuml
hide empty description

state SimpleOutput {
    SimpleOutput: description
    state out <<outputPin>>
}

state SimpleInput {
    state in <<inputPin>>
}

out --> in

state SimpleOutput {
    SimpleOutput: description
    state out <<outputPin>>
}

state SimpleInput {

}

out --> in
