It would be great to be able to upload an entire animation using the "Upload Only" option and then select certain frames to resume the rendering on so these frames can be checked to make sure they are rendering properly. And then be able to resume all if everything is good.
Currently I am working around this by uploading the animation with "Upload Only" selected and then cloning the project and rendering a couple frames. Which is clunky on my end and I am sure its not efficient on the cloud side of things either.
