Automate adding keys to encrypted partition with bash?

Question

bash

Hey! Tell me, plz, is it possible to automate adding keys to the encrypted luks partition using bash?
Example: There is a partition / dev / sda3 where you need to insert a key into slot 2. But since adding a new key requires entering an existing one, it becomes a little unclear whether this is possible in principle with automatization? I'll be happy to help, thanks in advance!
