Multiple Data Objects are added using the Plus button to extend the number of rows, more then one Data Object can be selected at the same time from the Workspace tree.  Selected row(s) can also be removed using the minus button.  Selecting a Data 

Objects key frame and right mouse clicking gives the option to “Toggle” the Data Objects on/off state.


Note: Folders can be added which benefits by making the rows less in the animator frames and that they can all be moved at once simplifying animation movements.
