regression: No way to set 'import-from' parameter since 3.0.1-rc2 #1236
Description
#606 introduced an import_from parameter to disks, which added the import-form parameter to, for instance, the --scsi[n] option.
This was removed in 5b89c2e#diff-104365919f693375882979581d9f36f5266991eef361948e56c220931fe886ddL600 and never re-added.
Is it possible to add this back?
It's really useful in order to import official disk images.
