Customising the title block

Hi all,

I am trying to customise a title block, all goes well until I want to insert the property 'Material'.

When I click the button 'Link to property' and go to 'Edit Custom Property List' I can see the property 'Material'

As stated in the help I can only 'Add', 'Delete', 'Move Up' and 'Move Down'

How do I insert this property?

Many thanks for your time in this,

Jeroen
