Customize CSS class name

GrapesJs editor creates a unique class for element and adds CSS rules to it. For example,

.c1731 {
    color: #FA8072;
    border: 2px solid #FA8072;
}

Now, is there any way to customize this behaviour? I want it to be .parent-namespace .c1731 instead of just .c1731?

.parent-namespace  .c1731 {
    color: #FA8072;
    border: 2px solid #FA8072;
}

Is there any solution to do so?

Thanks
