How to interrupt a Wait For Completion Action?

[Snowfrog]

My FSM has a 'Following Player' state that is the default state. In a script, I detect when the mouse is clicked and I trigger the 'MoveTo' transition event and set the Vec3 target of the mouse. This triggers a transition to the 'Moving To' state (right in the image) that has an action to Start a Behavior Designer Tree. That tree (left in the image) has a simple behavior, it seeks the target then waits for one second.

I have a bit of a conundrum because in order to make sure that Playmaker lets the behavior tree run it's course completely before going back to the 'Following Player' state, I seem to need to tick the 'Wait For Completion' option. The problem is that I want to be able to interrupt this 'Move To' execution if the player clicks somewhere else, effectively giving another 'Move To' order. How should I handle this situation?

In the state that waits, you can place other actions that can send events thus leaving to any state you want (e.g. also listen for input). Else you could use a second FSM that listens for input and that sends out an event to the first FSM to go to any state you want.
