Yes. In the parameter type drop down, you select Browse and then select the type of object you wish to pass. Use the "This" property of the object to pass it in. A handy way for figuring out the type is in the Object Explorer window, click the "Configure Type" button to bring up the window to select which properties, events, and methods you wish to make available in your automations.
