Disable label in tree based upon grouped column

Related products: Software Factory Web and Windows GUI Universal GUI

Currently when using a tree based upon a grouped column, the label of this column is displayed on top of the value of that grouped column. I would like to be able to disabled this label. Often I do not need this label and for some users this is very confusing. 

In this example I would like to hide the label text Ship Manager. All I have to see is the value “Athena Marina Co. Ltd. 

This will also keep the tree view much smaller, since currently this takes up two rows instead of one.
