Have a product (dresses) all the same exact that comes in 22 color choice, I currently have set up as separate products but I would like to merge into a single product with variants.  Any idea on how to do this besides manually??

Thank you!Do you think that it will "mess" with Google Merchant?

Also, if I did not have the one-size variant would that mess with google and the merchant center?

I sell a lot of jewelry on my e-commerce site, so I'm familiar with variants. However, when it comes to Necklaces, Bracelets, Earrings, and so on, "one-size" is the only evident size.Is it required to have a size variant in these kinds of items?

Does anyone know of an app this would allow a Wishlist AND a Cross-Device sign-in (such as Keep Cart). Just looking to install one app vs multiple.
