But the format must be the same eg Disks shows it. But sure if a Grub tool can show that, but worst case you'll be booted into a initrd BusyBox terminal where you can just look inside /dev/mapper and see the true path that needs to be entered.

Like this?

  └─sda6                                          8:6    0 406.2G  0 part  
    └─luks-f3fbb9ba-a556-406c-b276-555e3e8577bc 254:1    0 406.2G  0 crypt /home

That's groups of 8 4 4 4 12.

Cheers,
David.
