Hello Pilou - i like your lateral thinking as usual!
I attach the simple concept of the ideal way i would implement this if i was
a coder...No doubt other tools can acheive the same result...Was just wondering
if Michael might see the scope for this as an extension of the current alignment
tool...it seems we've found grey area between MOVE and ALIGN or ALIGN and MOVE.
Personally - i dont want to use "clicks" i just want the function to do it!
I said two clicks as a challenge - could it be one selection and one click and one command?!

See the attached please...

Kindest

Stefano
