Hi lyt_yudi

You can already do this, but it is not implemented in the GUI

mp0: local:102/vm-102-disk-3.raw,mp=/mnt/,size=1G
mp1: /dev/dm-3,mp=/mnt1/,size=1G


mp0 will mount here a disk image to /mnt
mp1 will mount the block device /dev/dm-3 to /mnt1 inside the container

I advise you the first synthax, as it allows you cool stuff like online
reszsing with pct resize
