Thank you Rik for both comments.

I am hopeful there is an fantastical solution that someone knows of that I can smack my head when we find out.

Actually, I've had situations where I've had 2 objects side by side, and the 3rd just doesn't want to snap below them in the centre.
This exercise has obviously shown why that doesn't happen?!
