LUKS key on SD card, any way to require password to unencrypt key?

I am currently in the process of setting up a fully encrypted Arch64 install on my Laptop, and I cannot seem to find anything about how to use a password to decrypt encrypted key to decrypt the LUKS partition. Is this even possible? And if it is, can someone point me towards how to do it?

Example:

Press power button -> GRUB screen -> GNU/Linux asks me for passphrase to decrypt key stored on SD Card -> GNU/Linux uses decrypted key from SD card to access a LUKS partition on my hard drive -> Continues booting as normal
