AutoCAD Inventor :: Equalize Material Appearances Globally In Whole Assembly In 2013?

In Inventor 2012 user has ability to change the material properties globally.

All parts using certain material will follow the changes made to properties and written to single library. It is clear and predictable.

In Inventor 2013 material properties belong to individual file.

When changes were done to appearance properties of a single part there could be situation when the same material parts in the assembly could have different appearance.

Here is the fact I do not understand and it is contradict to actual reality since the same material with the same standard must look absolutelly the same when switched to Master view.

Seems like to make parts look the same or to change the appearance I should click on each single file and make the same changes to each file.

I do not intend to change the appereance properties in single file on purpose to make problems to myself but I am sure I will take somebody else part and it will be changed due unnecessary reflection or other too much realistic things added in 2013. So finally I will get some sort of parrot collored assembly without clear and most importand easy way to make an order.

So I wish I could equalize all same material parts in apearance view. I do not count the way of clicking each file.
