iSCSI how to assign ports to targets after migration from CORE to SCALE

On CORE we had multiple iSCSI portals each associated with its own port

After migration to TrueNAS-SCALE-24.04.0 now with the portal there is only an option to select “” or “::” - which in turn associates the “iSCSI listen port*” from the “Target global configuration” tab with the portal. Effectively this means that it is not possible to have multiple portals or what are we missing?

Thanks in advance
