Plans for capability to import session elements into current session?

I haven’t been able to find something like this in the manual–besides the ability to save a session as a template, the ability to choose tracks or mixer elements from another session and bring them into a session already in progress. Very handy for anything involving bus sends into aux structures that you’ve already prepared. Similar to “import session data” in ProTools, but that’s the level of functionality we’re aiming for, right? And beyond?
