Aligning points along a path - or - mimicking another solid's points?

Hi everyone. First time poster here, so apologies if I don't get all the terminology right! :D

When 'aligning' the points of a solid object in MoI, there are only the options to align via horizontal/vertical center, top, bottom, left or right. Is there any way to align points to either a) a path/arc/curve, or b) to mimic the arrangement of certain points on another already-existing solid?

Thank you!
