custom prompt for system encryption password entry on startup

I have full disk encryption on my arch linux laptop. When i power on the machine it prompts me for my disk password. My system is encrypted by following the LVM on luks archwiki page. the prompt says something like "a password is required for the cryptlvm volume" i would like to change this to feature some imformation about the system like the owner and an address to return it to if lost. So far i have just tried to look at the arch wiki and search to see if anyone else had asked anything similar but i cannot seem to find anything.
