You can use components such as voltage control voltage source or voltage control resistor to emulate real-world phenomenal such as temperature.  For example, you can pretend the degree = 1mV so connect a DC source to the input.

You can use the Multisim symbol editor to draw part you want. You can access the symbol editor through the Component Wizard under Tools>>Component Wizard.  If you don't need to simulate this part, click "layout" only on step one.  The tutorial to create a new part is here:
