Is it possible to make the transistor act as a 3-terminal SPDT switch? If so, one transistor will be able to control two loads.- In general, can a SPST switch act as a SPDT switch?

Is it possible for one transistor to switch two loads?
The output collector-emitter part of a transistor can be thought of as a 2-terminal SPST switch controlled by the input base-emitter voltage or base current. So this _transistor switch_ can control only a single collector load. Is it possible to make the transistor act as a 3-terminal SPDT switch? If so, one transistor will be able to control two loads.
