Yes, you can have multiple circuits for your problem. BUT, the circuits must all be connected with a common ground. The circuit editor program requires all components to be connected to make a valid circuit.
To describe several electric circuits and keep the condition of connected circuit, it is necessary to add a connection between the circuits presented in the figure below.
These connections bear no influence on the electric behavior of the electric circuit. It is necessary to have the presence of an electrical ground (potential set to 0 Volt) for each connected circuit
