No GRUB "unlisted ISO" option in YUMI 0.0.1.6 for UEFI?

On the old YUMI tool for Legacy systems, there was a distribution option of "unlisted ISO" for using the iso rescue disk image from TrueCrypt. On YUMI 0.0.1.6 (UEFI), there is nothing like that in the drop down list of options. It's all just specific distros of linux, or specific tools like DBAN, Clonezilla, etc etc etc. There's no plain unlisted ISO option. What do I select in YUMI 0.0.1.6 to burn the ISO of a Veracrypt rescue disk?
