Perhaps just have the location of those textures directly next to eachother, so minor cutting and pasting is required? As much as perfectionism does hinder people some will want skins that are not symmetric. Like somebody making a robotic commando skin or something.
Edit- Made a mistake, but PuyoDead fixed it, thanks :smile.gif:

Yea, we've been asking for that one for quite a while. While it usually isn't an issue, it is quite a hindrance when you do run into it.
