Syncing temporary folders with iCloud

Hi everyone! I have very organized folders and files on my computer. At times I really need my project files to be shared and accessible on my iMac, MacBook Pro, iPad, and iPhone. What I need to do is to sync some of the folders with iCloud and after a few weeks remove them from syncing. Is that possible with KM?

Please provide the detailed, step-by-step workflow of how you do this manually. Then we can best determine how KM can automate.
