Apply changes in style mager to one class

Hi @artf, I noticed that when I used the style manager it applies the style to the whole class of the component selected

for example if i have a component that has class like this <div class="class1 class2 c1234"></div>

the style manager applies the style to

.class1 .class2 .c1234{
   color: #222222;
}

is there a way to apply the style only in ".c1234" class? something like this via style manager

.c1234{
 color: #222222;
}
