You can right click a link, and open it in the other container. It's clunky, but has worked for me so far. The UX for default containers could really benefit from some kind of context-awareness, but I'm not sure what that would look like. I'm thinking an intermediary tab that gives you a list of default containers (instead of only a single option or none at all) to choose from when opening a domain. Then, maybe, you could set a default choice based on the originating container. Or maybe a tree of sub-containers... This is where addon-defined UX makes sense.
