very specific unique drag and drop question

CONTEXT OF QUESTION
-------------------
Currently, I am creating a custom scheduler app in visual basic, and in that app, one can drag and drop appointments.

I know how to do all of the drag and drop procedure, and it works correctly.. I am using "label1.drag 1" to start the drag in the appropriate event, creating an outline of the appointment. but now I've come to a point where there can be underlying appointments and I must allow a user to drag and drop both the underlying appointment and the appointment on top of that.


QUESTION
--------
How can I make a more complex drag outline? i.e. using two labels at once. if I set the drag method on two things at once, visual basic only accepts the last one set.

thanks.

.. getting buried. I would really like some help on this from someone. I would really appreciate it.
