Hi Marklavin, hi folks.
Why would you want such a behavior ?
If it is to insure that the two objects always keep the same spatial relationship and that, if you, for example, rotate one and want the other to rotate as well to effectively maintain this relationship, I would suggest grouping the two objects together.
That way, any movement or rotation of the group will affect both objects at the same time.
If the purpose is different then, I have no idea unless you give more explanation.
Just ideas.
