You are not the only one. I cannot think of a single example where I would like to select 2 objects with one click.
When I searched for the thread I started for this, I learned that I actually started 2 threads already 
:
An option to make alt+shift+click the default behaviour - Dorico - Steinberg Forums (with a few nasty examples)
For now I always select everything with alt and shift keys pressed. (Only multiple selections are not possible this way, because cmd+click and alt+shift+click cannot be combined.)
