You can't. It's all or nothing. I think the main point of IPL is for the convenience of taking a photo, editing it, placing it in an album, and it is the exact same on your other devices. Apple just didn't explain this well. I don't think it's meant to be a separate cloud storage service, but maybe I'm wrong.
Also, I think that once your phone, etc. starts running out of space it automatically starts "optimizing" photos to free up space. Again, I may be wrong though.
