Two ways of "using" a structure?

[pspencil]

There is a Tardis mod available which transports the person using it randomly when right clicked. I am trying to add an additional function such that when left clicked, it will always teleport the player back to the base. However, it seems the only way to interact with a structure using left lick is the component "container" which is not what I want. I think I needs to define a new component, do I? If so, how do I link it to the event "left click"?
