Dear Alekhya,

Thanks for your post. You can add the activity diagram as diagram reference of the activities. More details of adding reference can be found at http://www.visual-paradigm.com/product/vpuml/demos/visualmodeling/refartifact.jsp

If there is any further inquiry, please do not hesitate to contact me.
