Update
Ok I think I ran into some troubles assigning the Advance Attribute on a Mac, running Bootcamp version of SketchUp wasn’t problematic. (I do hope the developers will give some more 
to that platform…Noticed the version numbers? Mac just to be one digit ahead, now Windows is the first
I have updated the ‘Status Owner’ report in Windows and assigned some of the advanced attributes.
Basically, those advanced attributes consist of two seperate sets:
SU_Definition set (Price, Size and Url)
SU_Instance set (Owner, Status)
AA can thus only be aplied to Components, but there are quick ways to assign them. eg. Price, Size and Url can be assigned when creating them, but you can also select different components and set them all at once in the entity info, afterwards. (This however, can not be ‘Undone’ ) Probably another bug?
Same goes for instances of the definition, you can select multiple different definitions and apply the same attributes.
As always, best to name components for better control in Outliner.
which results in:
Here is the updated Model:
