How to assemble subassemblies?

[magnemoe]

This is making me crazy. you can only attach by root nodes, if you make an group of parts an subassembly the splitt is the root node, this is nice for boosters and similar.  
However if you design stuff like rovers or landers and want to launch with mothership this don't work well. 
The problem is that 1.12 reset control from here then it reload the craft. Burning the wrong way is not smart, espesialy then close to other crafts or in low orbit. 
Worst on small high twr probes who is most practical to launch with other ships. 

Anybody have any tips here, outside of launching stack upside down or seperate and dock in orbit

I can't quite visualize the problem that you are talking about. Can you show a picture? Are you aware that you can rotate the subassembly with the WSADQE keys?

I use a probe core or docking port on top of the part that you attach the sub assembly to and before launching (or what ever) click on it and select "control from here".
