Steam too GGG

Is there any way to bring all my achievements, and supporter packs from Steam over to the GGG website for my account, thank you in advance, also loving P.O.E., best game, ever.

You can link your established Steam-authenticated account with this website-authenticated account, but it will unlink any characters on this website account. If that's fine, ask support@grindinggear.com to do this.

Don't use the steam linker, because it would just unlink your Steam account with all the goods on it.

Thanks.
