Stop Export at Set Time

Hi all.

My colleague exported a sequence from Unreal overnight and when he came in this morning, unreal had exported 178,000 even though the timeline is much, much shorter than that.

I have been told in the past by my boss ‘press Esc when you see the camera just looking at the sky’… so nobody in the office knows how to stop the export at a desired time.

So, my question is: How can I stop an export at a chosen time.

I presume something has to be done to the blueprint but I don’t know where to start. I’ve attached a screenshot of the current blueprint. Can something be added to that? If not, can you have multiple blueprints?
