You cannot create a VLAN interface without specifying the attached interface.

Also you can create the a VLAN 100 interface on port1, and another VLAN 100 interface on port2.

Depending on the model of your FGT(s), you can use either hardware switch, vlan switch, or software switch to bind port1 and port2 into one logical interface then assign a VLAN 100 subinterface on it. Be aware that once you bind them into one interface, you can't configure each of them separately. 
FGTs are not L2/L3 switch so VLAN operation is limited.
