Can we share and duplicate team boards?

Unless I'm missing something, I don't see a way to duplicate a team board within my own 3DLean app, nor do I see a way to share a board with someone else. It'd be great to be able to perform these actions so we can leverage team board templates without having to recreate from scratch every time (and carry along assets like images when doing so). To take it a step further, it'd be great to have a template library we could choose from (and add to) with a menu to select a blank team board (or regular board) or select from a template in the library.
