Abort Button for Automation Designer

It would be great, if there would be a Button in Automation Designer to abort the run of an App. Sometimes I hit "Run from here" by accident, when I just want to execute one action in the App or I remember I forgot something just the moment I executed the App.
There is no way to abort the execution of all following actions in the App then, which gets pretty anoying, when there are actions that take a lot of time (large imports and stuff like that).
