I need to correct myself a bit:
When copy-pasting only Dimensions, only those Domension Points of Dimensions will go through that are set to Static (it is possible that within a Dimension Chain only some of the Dimension Points are static, others are associative).
So you should set all dimensions you wish to copy to Static.
That way all your dimensions will go through.
(If you copy both the dimension and the element it dimensions, everything will go through.)
