You can! Create "Friends & Family" Isolated NWC connection and use that connection string for another Alby Account ("Wallet Configuration" -> Link Your Node -> NWC). Then this user of Alby Account will have getalbycom lightning address and a wallet interface, using your Alby Hub. You can make multiple such connections, each with separated balance. You can reuse that NWC connection string to use same wallet in Alby Go and in Alby Extension as well!
