One way I can think of is the way a connector with many redundant connections to 
the same conductor works.  They all have the same pin name in pcb, and in the 
gschem symbol, there is only need for one pin with the matching name.  That way 
requires attaching your heatsink zone to a net as  a symbol in your schematic.
Then DRC will make sure your heatsink zone is there, and won't complain about 
unconnected pins.

Is there a way to have DRC not complain for a no name pin?  I think yes, but 
have not tested it.  Then the pin name would be null, "", or no such attrib 
attached.  The DRC would find proximity trouble, but would not ensure the 
heatsink zone was included.
