P: Adjustment lock feature for Sliders when applying Presets

Hi guys! I have a suggestion for the Lightroom app, can you add an adjustment lock feature? For example, let's say I want to lock the exposure at +1 and then I want to add a preset on the photo, but the preset includes a +3 adjustment, so this way I can apply a preset without changing the adjustment that I locked and in the preset browser I can view the small thumbnail with how the photo will look like if I apply the preset on the photo with that locked adjustment. I think it's a useful small feature.
