[PCB_FORUM] same symbol - different number of pins

Hello All.
 
Is there a solution for such component in ConceptHDL:
LM1117 from National:
 
DTX type = TO252 3 pins
MPX type = SOT223 4 pins . the fourth is the tab that has to be connected to 
OUT pin 2.
 
How to do it to:
-have only one symbol body
(I think without any "tab" pin. I tried with 2 versions on with the TAB the 
other without. But Add Part only take version 1 by default.)
 
-Connect this TAB automatically to pin 2 OUT
(I tried to add in the parttable to MPX type a PACK_SHORT='(2,4)' but 
unsuccessfully.)
 
- Select anyone of both different type in a single parttable..
 
Thanks in advance.
 
 
PS. This case seems to be a common problem. By searching "regulator tab" in 
sourcelink, it returns a case for a MC7805CT2 (or 3).
http://sourcelink.cadence.com/docs/db/kdb/1998/July/1816165.html
but the test2_archive.zip contains only a body with the tab, but selecting a 
new one shows a 3 pin JEDEC and the import logic returns a "incorrect pin 
number".
So this test2 does not work.
They speak about a multipin.tar available on ftp.cadence.com but this FTP site 
is unaccessible.
Does anybody get it somewhere?
