Creating New Docker VM with existing Docker .img files

[cal*]

I'm trying to migrate my Docker VM from one freenas box to another. When I try create a new Docker VM the UI won't allow me to select a .img file that already exists. Do i just need to create a bhyve VM with the exiting files as a raw file device?

Looks like this was a change from 11.1 to 11.2.
