[The Trashman]

I'm doing a theme team for my current run, and while I figured out how to give myself all the other Pokes I needed, the last one I need is Zygarde 10%, which I couldn't make with the tools I had. Would someone be able to convert the regular Zygarde I have right now into its 10% forme? I played through Gym 1 because I thought they'd let me do it myself in the Help Center where you start the Zygarde cell quest. Thanks.
