In the animation settings make sure "Frames Output" is checked so that KS saves the individual frames. (really, you should always do this. you can leave "Video Output" unchecked). When you need to stop and then start it again, you can pick up from the frame where you left off by choosing "Frame Range" at the top and entering the frame number you want to resume from and stop at. Once you have all 600 frames completed, you can import the sequence of images into Premiere or After Effects or even Photoshop (or any other video editor of your choice) and export your final video from there. This was possible in 2018 so, I'm not sure why no one mentioned it in that post you linked to.
Just an FYI concerning that post you linked to. One of the posts said:
"It would be great to have this feature on network rendering as well. I'd love to be able to pause a job during work hours and resume for the night."
It's possible to do that now. Figured I'd mention it even though you're not using a network.
