Scaling scenery objects for usage in children

I have a couple questions for knowledgeable scenery designers:
If there is a scenery object from some DLC and I scale it to shape it as I need it:
1- Is it possible to save the newly scaled object under a different name?
2- If the answer to 1 is yes, what is being saved, a new GeoPcDx or just the data for the scaling (with same Geo info)?
My intention would be using the new object in a child for rolling stock, what should I take into consideration, addressing to a newly formed object or take the scaling data to edit the child positioning matrix. Is it possible using that scale data from the object after scaling?
