Pause button / Add queues without starting the calculation immediately

I currently run into the situation that i want to run several tasks in the same workflow after each other. It is an image to video workflow. And so i drop image 1, and press the queue button. But when i press the queue button then it immediately starts to calculate. An with adding the second image i can already run into trouble since my pc can become inresponsible because of the already running calculation.

I also noticed that dropping the second image and clicking at the queue button can lead to an oom for the current running workflow. It steals memory for a short moment.

It would be great when we could set up our queues beforehand, and then start to run everything.

Kind regards
