I like modding things. I often get a character model off the hub, and then mod it. What do I do if the OP updates the model my customized one was based on? I think if I apply my modded appearance preset, it will undo the updates the OP did on their model. IOW, if the OP fixed some of the morphs that had issues, how do I apply my mods to the updated base? I only want to keep the "deltas" between the original and my version.
