Add Feature to Cancel Entity Deconstruction

Many times, I've hastily queued the deconstruction of a warehouse full of inventory, then changed my mind after it became clear that it would take a prohibitively long time to empty the entity storage. A cancel option would be welcome.

So, I realized that you can "cancel" the empty inventory function by moving the slider into the green. Unfortunately, I didn't see this documented in any of the tool tips or contextual guidance. Therefore, might I suggest this functionality be better communicated to the player to minimize frustration?

Damn, I didn't know that!!! Intuitively, I was trying to push on red product icon in hope to cancel my harsh decision, and having no result, I was thinking it is impossible. Maybe make it work like that at least?

While you can go to each entity and pause. There is no brush cancel. That needs to be there, I hit Bulldoze vs Pause when I was in mas hurry to get some needed employees. Immediately realized my mistake, and pause the game, I had to go to each an Every every section of the factory, including connectors and cancel them, had reach under belts, and still missed some items that needed replacement later. I brush Cancel would have been very helpful.
Is there some key actions I am missing?
