LESS: Selecting one of several parent selectors

I'm almost certain there's no way to do this since I've searched a looot, but anyway hopefully...

I have this LESS code:

.parent-one, 
.parent-two {
     .child-of-both {color: #fff;}
     .child-of-one {color: #222;}
}

I want the "child-of-both" to be outputted as it is, meaning for both parents, but "child-of-one" exists only in the "parent-one" and ".parent-two" be ignored, so the output needs to be only:

.parent-one .child-of-one {color: #222;}

Is it possible ?
