I think what you're looking for is a "group".  When you use groups,  
you define a particular name, and when you encrypt to this name, you  
actually encrypt to everyone in the group.

 From the sample gpg.conf file:

# Group names may be defined like this:
#   group mynames = paige 0x12345678 joe patti
#
# Any time "mynames" is a recipient (-r or --recipient), it will be
# expanded to the names "paige", "joe", and "patti", and the key ID
# "0x12345678".  Note there is only one level of expansion - you
# cannot make an group that points to another group.  Note also that
# if there are spaces in the recipient name, this will appear as two
# recipients.  In these cases it is better to use the key ID.
