It is possible to set up multiple VLANs on a single interface. As suggested by DKKDG you just need to create one. If you want to refer to any KBAs, please check these Sophos UTM - How to define a network interface and check Ethernet VLAN type.
Are there any KB's that also explain how to handle the NAT and Masquerade aspects when creating Vlans... I would think it would be the same as any other but wanted to check.
