How to cancel from prompt method in the code?

[EyalRELJT]

I am using with this method in my code:
Autodesk.Revit.UI.UIDocument.PromptForFamilyInstancePlacement.

My problam is that with this method, In a single invocation, the user can place multiple instances of the input family type until they finish the placement (with Cancel or ESC or a click elsewhere in the UI).

I want to exit the method after the user places one element.

So i create an event - DocumentChanged, and that's how I can know when the user places an element.
My question is how do I get out of this method (PromptForFamilyInstancePlacement)? Is there any method to do this?
Thanks
