I think Physical design reuse (PDR) is far out of scope of the group 
selection idea. However it Might be used. I actually put some thinking 
on howto implement some kind of PDR into Kicad without having to 
redesign everything existing already. Its in a google doc with comments 
enabled.

[Google docs link]
https://docs.google.com/document/d/1ivRRu7F2g6_WU9bgHlaUTaXZw02oluMh4NA41BqEM-8/edit?usp=sharing

PDR discussions I think should be in a separate thread, since the amount 
of work to get there is quite a bit more, involves both eeschema and 
pcbnew, new file formatting, specifying workflows etc etc.

Its called snippets in A****m, PDR in PADS.
