Map Applied Core Material Title to TitleBlock

I am setting up a new TitleBlock and want to map the Applied Core Material Title to cell in the TitleBlock
When I want to Route the content from presented product it will not automatic collect the Applied Material Title. I need to select the material assigned to the Physical Product before data is shown in the TitleBlock. What is the right process to secure automatic mapping of the Applied Core/Cover Material? 

Another Question in same context:
When I compute the Weight definition on the Physical Product I can get both Weight, Volume and Surface area from the Characteristics Extension Package - Computed characteristics, but no information from the Core Material the Computed Weight is calculated. So again what is the right process to collect the Applied Material information data?
