Editing Faces - Change One DDLB Shouldn't Change All

I think editing player faces needs a little tweak - when change any one of the DDLB's, ex "Faceset", can we leave the other two set to their current setting? This way if we see we want to simply change skin color but keep hairdo, we can change "Faceset" and "Face" and "Hairstyle" stay assigned to the value they were already at. As is, as soon as you change any one of the three values, the other two values immediately reset to the default, ie first, value. Just a little thing but irks me
