TrueNAS over iSCSI: Snapshot Management

I'd like to get some input on snapshot management relating to TrueNAS. Currently, Proxmox does not allow for multigeneration rollback of snapshots.

TASK ERROR: can't rollback, 'preupgrade' is not most recent snapshot on 'nas:vm-803-disk-0'

I was wondering if there is a way for Proxmox to allow for the use of TrueNAS periodic snapshots without breaking Proxmox snapshots.

Is there a way to import TrueNAS snapshots into Proxmox via the API?

Could multi-generation rollback work because TrueNAS supports it?
